Alternate Title

Field Book No. 1, Notes 4c


The field book documents William Dall's survey work in Alaska during 1871 as part of the United States Coast Survey. Some entries are dated and include information about travel and weather. It mostly contains notes on methods of use and placement of survey equipment for acquiring needed data for survey work and the collected survey data. In dated entries, it includes measurements and signal locations for vicinity of Ulakhta Harbor [Dutch Harbor] and Small Harbor [Small Bay]. Additionally, there is a report on meteorology, tides and currents around Unalaska.

Anchor off the town in 19 fms, soft muddy bottom about 3 P.M. Rains [[line]] Sept 24. Sunday [[line]] Morning clear & fine. P.M. rains a little. [[line]] Sept. 25 Monday [[line]] Make sail and stand into Ulakhta Harbor. Anchor in 20 fms shingle about 10. A.M. Take the gig & first cutter with signal lumber and search for any monument or sign of Mr. Davidson's astronomical position, without success. His station must have been near the end of the spit but no trace of it is left, nor of the house mentioned in his Report.

Heights measured with Casellas altazimuth. Measure off a line very carefully with Chesterman's steel tapes & find that at 200 ft the space between the upper & lower horizontal wires of Theodolite No. 97 covers a space of sixty divisions on telemeter no. 97. Go to head of spit and select a place for a second primary station to make the other end of the baseline

After setting up this signal put up a small stick on the West side of the head of Ulakhta Harbor 30 fee above water, ten or twelve feet in shore (Gull Rock.)

Return to vessel at 1 P.M. Start at 2 P.M. for Rocky Point and erect a signal 35 feet above water Pole 20 ft 6 in above ground cross pieces as before. Then erect another (Round Top) on a small hill on the middle isthmus of Amaknak Id. Pole 20 feet high. Height above water undetermined. Return to vessel at 6 P.M. Harrington & Capt Hall spend most of the ascertaining the astronomical azimuth & mean time. Weather fine brisk SW Wind. Sky with occasional clouds.

Winds light. At 4h Sept 3, nautical time the temperature which for a few hours had fallen to 58° abruptly rose to 62° and the observations showed a change of direction of the current toward the west. The temperature increased to 63° on the 3rd at 20 [[underlined]] h [[/underlined]] and continued for about 24 hours when it fell to 62° again and the observations exhibited a slight northerly & westerly drift of about .2 knots per hour. On the 4th at 24h the temperature rose again reaching 65°

This culminated in the 6th at 8h in 67° after which it fell rapidly to 64° which continued for the remainder of the day, and results of the observations showed a strong northerly [[insertion]] & westerly [[/insertion]] current about 45 or 50 miles broad.

The observations even indicated a very slight northerly drift during this time, which I am inclined to ascribe to an excess of leeway, from the direction of the prevalent winds. After 24h on the ninth Sept. the temperature fell simutaneously with a succession of SE gales which obliged us to lay to, for two days and prevented astronomical observations being made. The wind gradually moderated and the temperature decreased but we were still unable to obtain any sight of the sun or other heavenly bodies for four days. On the 13th the temperature had fallen to 52°, which has

Here in lat. 48° 40' and lon. 152°.35' d.r. a sudden and very remarkable change of temperature was experienced being an abrupt rise from 52° to 65°, the temperature of the air, though behind that of the water changed in a similar manner, and [[strikethrough]] again [[/strikethrough]] we sailed over this hot stream for 12 hours when the temperature fell as abruptly as it had risen, to 51°. The width of the stream was about forty miles in an east & west direction. The impossibility of getting any astronomical obs. unfortunately prevented our determining its rate & direction although I am of the opinion that it was raining in a nearly due south direction.

It appears from the directions of the current and from the latitude ([[underlined]] 5Q [[/underlined]]) and other general considerations as if this period was passed in crossing the elbow of a ^ [[insertion]] southerly [[/insertion]] curve of the great N Pacific current.

The wind had been northerly for some days, and a heavy snow storm prevailing at the same time the result was that a large amount of slush ice in cakes had accumulated at the head of Captain's Harbor. The wind changed to a light southerly air and the tide being nearly high, about nine A.M. with the tide an immense quantity of this ice in rounded cakes & loose slush came into Iliuliuk Harbor through Amaknak Straits at the rate of 4 knots an hour filling the en [[/left margin vertical line]]

The water simply backed up at the NE mouth no current running in there The temperature was very low (20° Fahr) and most of the ice cakes froze together as soon as they became quiet so but little followed the ebb tide south the way it came but none whatever went out by the NE mouth showing that the tide does
