Supplies.-Fuel oils, provisions, water, and ship chandler's stores can be obtained at Eureka. Coal can be had in limited quantities only.

Repairs.-Minor repairs to machinery and to woodwork above water can be made. There are no drydocks or marine railways.

A Coast Guard station is located inside the north spit, 1/2 mile northward from the end. A look-out tower is located on the seaward side of the spit, abreast the station.

Communication is by rail to San Francisco, and by regular lines of steamers plying between Columbia River, Coos Bay, Humboldt Bay, and San Francisco. There is also considerable irregular traffic in large launches to various local points north and south. A United States naval radio station is located on Table Bluff. Communication may also be had by telegraph and telephone or by commercial radio at Eureka.

Tides.-The mean range of tide at Eureka is 4.8 feet (1.5 m). The range between mean lower low water and mean higher high water is 6.7 feet (2.0 m). A range of about 11 feet (3.4 m) may occur at the time of maximum tides. Daily predictions for Humboldt Bay (South Jetty Landing) are given in the tide tables published annually in advance by the United States Coast and Geodetic Survey.

Currents. The tidal currents follow the general direction of the channels. In the main channel the average velocity at strength is less than 2 knots, and the maximum does not exceed 3 knots. Between the jetties the average velocity at strength is about 2 knots, with a maximum of about 4 knots.

DIRECTIONS, HUMBOLDT BAY

A pilot should be engaged by strangers if there is any sea on the bar or if they have deep-draft vessels. It should be borne in mind. that the bar is subject to change, so that strangers cannot rely on finding the charts correct or the buoys indicating the best water. From southward.—From a position 1 mile westward of Blunts Reef Light Vessel a 30° true (N. 7% E. mag.) course made good for 231⁄2 miles leads to Humboldt Outside Bar Lighted Whistle Buoy. At night Table Bluff Lighthouse should be made shortly after passing Blunts Reef Light Vessel, and when nearing the entrance the lights in Eureka will be seen. In thick weather, after passing False Cape Rock, all dangers will be cleared by keeping in a depth of over 15 fathoms (27.4 m) until up with the lighted whistle buoy, where anchorage should be made until a pilot is obtained.

From northward.-From a position 3 miles westward of Trinidad Head Lighthouse a 187° true (S. by E. 1 E. mag.) course, made good for 17 miles, leads to the lighted whistle buoy.

On this course Table Bluff Lighthouse, 5 miles southward of the lighted whistle buoy, should be made ahead. In thick weather the depths should not be shoaled to less than 20 fathoms (37 m) between Turtle Rocks and Trinidad Head, and when southward of the head the depths should not be shoaled to less than 15 fathoms (27.4 m) until up with the lighted whistle buoy, where a vessel should anchor until a pilot is obtained.

From seaward.-Vessels can stand in boldly until sure of their position, when the course should be shaped for the entrance. In clear weather, the high land of Cape Mendocino and Punta Gorda southward and Trinidad Head northward of the entrance are good landmarks. At night the lights are a good guide. In thick weather soundings should be taken frequently, and upon getting depths of 30 fathoms (55 m) or less great caution must be exercised until sure of the vessel's position.

Sailing vessels during the prevailing northwesterly winds of summer should endeavor to make the land in the vicinity of Trinidad Head, which gives them a fair slant for the entrance, and is an additional precaution against the irregular southerly set of the current. In thick weather soundings should be taken constantly when inside of 50 fathoms (91 m). Making the land northward of the entrance avoids the irregular bottom and dangerous currents in the vicinity of Cape Mendocino. The description of the features of the coast are given under the heading "Coast from Cape Mendocino to Point St. George ", page 149.

From the lighted whistle buoy: Due to the frequent changes in the entrance, no directions of permanent value can be given. The latest chart and the buoys are the guides. Once inside the bay, the channels are well marked by beacons and buoys and are easy to follow.

COAST FROM POINT ST. GEORGE TO CAPE BLANCO (CHARTS 5702, 5896, 5951, 5952)

From Point St. George to Cape Blanco, a distance of about 60 miles, the coast trends in a general northwesterly direction, with a shallow bight, Pelican Bay, immediately northward of Point St. George. The beach is fringed by numerous rocks and sunken ledges, but, with the exception of Rogue River and Orford Reefs, these in general do not extend over 1 mile from shore. The 30-fathom (55 m) curve follows the general trend of the coast, and in thick weather may be considered as the limit inside of which it is unsafe to approach, but in the vicinity of Rogue River and Orford Reefs the depths should not be shoaled to less than 50 fathoms (91 m).

For about 10 miles northward of Point St. George sand dunes, with a broad sand beach, extend to the mouth of Smith River. Lake Talawa and Lake Earl, surrounded by low, marshy land, lie behind this stretch of dunes.

A small rock, about 20 feet (6.1 m) high, lies 134 miles south of the mouth of Smith River and nearly 11⁄2 mile offshore.

A cluster of three low rocks lies nearly 1 mile offshore and 11% miles 200° true (S. mag.) from Prince Island.

Pyramid Point, a rocky knoll 213 feet (65 m) high, marks the north point of Smith River.

Prince Island, of small extent and 171 feet (52 m) high, lies mile offshore abreast Pyramid Point. Hunter Rock, 177 feet (54 m) high, double-headed and somewhat smaller, but of the same elevation, lies 1/4 mile north of Prince Island; several other smaller rocks are in the vicinity.

Between Smith River and Chetco River, a distance of nearly 7 miles, the coast is composed of low, rocky cliffs, bordered by numerous

rocks and ledges, sunken and awash, and is backed by a low, narrow tableland. Several prominent, rocky knolls rise from 100 to 200 feet (30.5 to 61 m) above this tableland. The Winchuck River, a small stream with 11⁄2 mile of low sand dunes on the south side of its mouth, empties 3 miles northward from Prince Island. The outermost rock awash lies nearly 12 miles offshore southwestward from the Winchuck River, or 234 miles 335° true (NW. % W. mag.) from Prince Island.

Cone Rock, nearly 11⁄2 miles northward of Prince Island and over 1/2 mile offshore, is the most prominent of the visible dangers in this vicinity. It is 68 feet (20.7 m) high and of small extent. The remaining dangers are too numerous for description, and this stretch. of coast should not be approached closer than 111⁄2 miles.

Chetco Cove (chart 5896), at the mouth of the Chetco River, is 151⁄2 miles northward of Point St. George. It affords an indifferent anchorage, with some protection from northwest winds, but is exposed in southerly weather. There are numerous visible and sunken rocks fringing the shore of the cove and its approaches, necessitating caution in its use. At the middle of the cove is a sand and gravel beach over 1/2 mile in length at the mouth of the river. From southward the valley of the river is well marked even in hazy weather.

On the north shore of the cove, westward from the mouth of the river, is a sawmill about which has grown the post village of Brookings, population 250 (1930 census). The three stacks of the sawmill are prominent from southward.

A wharf with its piling resting on rock has been built out to 25 feet (7.6 m) at mean lower low water, with 18 feet (5.5 m) at the inner end of the loading face. Heavy mooring lines, secured to the rocks, pass under the wharf. Vessels moor to these lines and to mooring buoys without touching the wharf, and load lumber. Vessels load to a maximum draft of 2312 feet (7.2 m). The sector of approach to the wharf is between the bearings 353° true (NNW. 2 W. mag.) and 18° true (N. 14 W. mag.) to the end of the wharf. Shoals of 334 fathoms (6.8 m) lie just east of this sector and a shoal of 42 fathoms (8.2 m) lies just west of this sector.

Lumber schooners waiting to go alongside the wharf usually anchor in the vicinity of the whistle buoy in 16 or 17 fathoms (29.3 or 31 m). Anchorage may be had farther in, in 8 to 10 fathoms (14.6 to 18.3 m) but the bottom is rocky and very irregular. The sawmill has been closed for several years. Water and gasoline are no longer available at the wharf. Plans were being prepared to resume operations at the mill in 1934.

There is a whistle buoy located 1 mile southward from Chetco Point. On two occasions a silent zone has been noted about this buoy. It was heard at a distance of 3 miles, then the sound was lost, to be picked up distinctly at a distance of 1/2 mile.

No directions are necessary.

From Chetco Point to Cape Ferrelo, 42 miles, the coast is composed of high broken cliffs bordered by numerous rocky islets and ledges extending in some cases over 11⁄2 mile offshore.

Goat Island, 184 feet (56 m) high, lies 2 miles northward from Checto Point and 500 yards offshore. There is deep water off its western and southwestern face, but rocks and foul ground extend

200 yards southward from the southeastern point. The island is readily identified. Its profile closely resembles that of Prince Island off the mouth of Smith River.

Cape Ferrelo is the first prominent headland north of St. George Reef, and, while not projecting seaward to any considerable extent, is noticeable on account of its bold, rugged face. Several rocks and islets lie directly off the cape to a distance of 1⁄2 mile.

From Cape Ferrelo to Crook Point the coast is very rugged and rocky, with several large and prominent rocky islets and reefs extending well offshore, forming, in some cases, anchorage for small vessels in northerly weather.

Whales Head is the outer of two rocky islets 128 feet (39 m) high, 214 miles northward from Cape Ferrelo. A rock awash lies 800 yards southward from the highest point of Whales Head.

A rugged cliff from 200 to 300 feet (61 to 91 m) high lies 314 miles northward from Cape Ferrelo. The face is about 1 mile in length and behind it rises a treeless, triple-headed hill to heights of 700 to 800 feet (213 to 244 m)..

Leaning Rock, 77 feet (23.5 m) high, lies close inshore, 31⁄2 miles northward from Whales Head; it has a perpendicular face on its northwest side and slopes gradually southeastward. Several other rocks are in its vicinity.

Between Whales Head and Crook Point are two prominent, apparently grassy, areas in the forest near the crest of the hills, about 2 miles apart and situated at an elevation of nearly 2,000 feet (610 m); the southern one is known as Rocky Prairie. These are noticeable when off this section of the coast.

Yellow Rock, 84 feet (25.6 m) high, lies 42 miles northward from Whales Head, and 11⁄2 mile offshore. The rock is yellowish in color and can be recognized from 4 miles offshore.

Bosley Mountain, 3,403 feet (1,037 m) in height, from westerly and northwesterly positions offshore, shows above the coast ridges as flat-topped, with two summits separated by a slight depression. From offshore what appears as the northeasterly summit shows rounded, and appears somewhat larger and slightly lower than the eastern summit.

Mack Arch is a double-headed, rocky islet 3/4 mile offshore, 12 miles southward from Crook Point and 8 miles northward from Cape Ferrelo. The western head is 231 feet (70 m) high and the eastern a little lower; both are black to near the summits, which are generally white from bird droppings. The arch, about 40 feet (12.2 m) high, is under the eastern summit and shows prominently from southward. A rock awash lies 125 yards southward from the eastern point.

Anchorage. The bight to the eastward of Mack Arch has been used as a temporary anchorage during moderate northwest weather. The rocks and reefs break the swell. In approaching the anchorage, pass to the southward of Mack Arch about midway between it and Yellow Rock. Anchor in 11 fathoms (20.1 m), sand bottom with Mack Arch bearing 296° true (W. 12 N. mag.) and Yellow Rock bearing 155° true (SE. mag.). No breaks were noted, but caution is to be exercised as the place has not been closely surveyed. There is a farm in the cove to the northeastward of Mack Arch.

Mack Reef extends from Mack Arch to Crook Point, and is a collection of some 30 rocks, visible or sunken, varying in height from awash to 110 feet (34 m). From southward these rocks stand out conspicuously when seen against the white sand dunes northward of Crook Point; Mack Arch, on account of its size and height, being the most prominent.

Mack Arch Cove (chart 5896) lies immediately eastward of the reef and affords fair shelter in northwesterly weather in 6 to 7 fathoms (11.0 to 12.8 m), sandy bottom. In entering from southward, pass eastward of Mack Arch, giving it a berth of about 150 yards, but taking care to avoid the rock 125 yards southward of its eastern point. Then bring the 125-foot (38 m) rock, the highest of the northern part of the reef, to bear 352° true (NNW. 5% W. mag.) and steer for it on that bearing until up to the anchorage abreast the group of rocks 1/2 mile northward of Mack Arch. Local steamers drawing less than 12 feet (3.7 m) find smoother water by continuing the 352° true (NNW. 5% W. mag.) course through the kelp and anchoring in 4 fathoms (7.3 m) with the 125-foot rock bearing 333° true (NW. 14 W. mag.), distant 300 yards. This latter anchorage is contracted and is not recommended.

Crook Point is moderately low, but terminates seaward in a rocky knoll 175 feet (53 m) high, with a slight depression immediately behind it. The rocks close to the point often show up during moderately thick weather, several being of very noticeable pinnacle. formation.

From the vicinity of Crook Point to the mouth of the Pistol River are sand dunes which show up prominently in clear weather and distinctly mark this section of the coast. In thick weather these dunes can not readily be distinguished. From the mouth of the river to Cape Sebastian are numerous rocks and rocky islets extending 11⁄2 mile offshore, reaching in some cases a height of 150 feet (46 m). Cape Sebastian is prominent from either northward or southward. It is the seaward termination of a bridge transverse to the coast, and rises abruptly from seaward to a height of 694 feet (212 m), with a depression behind it, and then more gradually to a height of about 2,000 feet (610 m). The seaward face is precipitous and broken and has a few trees; southward the lower part is grass covered. A sunken rock with 11 feet (3.3 m) over it at low water, seldom breaking, lies 1/2 mile offshore, 7% mile, 342° true (NW. 12 W. mag.) from the western extremity of the cape.

Hunter Cove (chart 5896) is a small, contracted anchorage under the southeastern face of Cape Sebastian. It is formed partly by the cape and partly by Hunter Island in the entrance. The island is 1/4 mile in extent, rocky, flat-topped, and 113 feet (34 m) high; shoal water extends from it eastward to the beach. The cove is used occasionally by launches and small craft. During strong northwesterly weather, the sea at the entrance is rather lumpy for small boats. There is a small stream at the head of the cove which furnishes good clear water. With moderate south westerly weather a heavy sea piles up across the entrance between the cape and Hunter Island. The cove is not recommended as an anchorage.

From Cape Sebastian to the mouth of Rogue River, a distance of 6 miles, the coast is considerably broken and quite rugged, but
