picture art. The Indians think that it was made prior to Indian times. Apparently it belongs to the same order of pictures as the drawings on the rocks of Lake Chelan and other places in the north-west, furnishing a worthy theme for the antiquarian.
The other object of historical interest is the remains of the temporary fort built by David Thompson of the North-west Fur Company in 1810. Thompson crossed the Rockies in that year in order to descend the Columbia and gain possession of its territory for his fur company. He was a brave, intelligent, and enterprising man with considerable knowledge of astronomy. But he waited one season too long. For, finding it late in the year 1810 when he had reached the sources of the Columbia, he decided to winter there and descend the River in the spring. He selected a beautiful spot capable of defence on all sides on Lake Windermere and there built a rude fort, the trench and mound of which still remain. In the spring of 1811 he went down the river (and this was the first party to traverse the entire course of the Columbia) full of hope that he might take possession for Great Britain and the North-westers, only to find that the Astor party of Americans had preceded them by three months in effecting what might be called permanent occupation.
This was one of the important links in the history of the control of the North-west. Doubt has been raised as to the authenticity of this Windermere location, but there are certainly the remains of mound and trench, and the tradition has it that here was the place of the Thompson party of 1810, the first place located by white men on the upper Columbia.
