Dried Salmon at Celilo Falls

On October 22nd, 1805, at Celilo Falls, William Clark wrote about the great quantities of dried salmon observed there:

...the waters is divided into Several narrow chanels which pass through a hard black rock forming Islands of rocks at this Stage of the water, on those Islands of rocks as well as at and about their Lodges I observe great numbers of Stacks of pounded Salmon (butifully) needy preserved in the following manner, i e after Suffiently Dried it is pounded between two Stones fine, and put into a speces of basket neetly made of grass and rushes of better than two feet long and one foot Diamiter, which basket is lined with the Skin of Salmon Stretched and dried for the purpose, in theis it is pressed down as hard as is possible, when full they Secure the open part with the fish Skins across which they fasten tho' the loops of the basket that part very Securely, and then on a Dry Situation they Set those baskets the Corded part up, their common Custom is to Set 7 as close as they can Stand and 5 on the top of them, and secure them with mats which is raped around them and made fast with cords and Covered also with mats, those 12 baskets of from 90 to 100 w. each (basket) form a Stack. thus preserved those fish may be kept Sound and Sweet Several years, as those people inform me, Great quantities as they inform us are Sold to the whites people who visit the mouth of this river as well as to the nativs below.
