Week 47-part2 of around Portland. Journaling reads:
Scappoose is on the site of an old trading post and farm of the Hudson's Bay Company. It was here that the great Indian highway, later the Hudson's Bay trail between the Columbia River and the upper Willamette Valley, had its beginning. Scappoose appears to have been a great trading center for the Indians on the lower Columbia. The virulent disease which almost wiped out the Indians of the Sauvie Island region began among the Indians at Scappoose Bay and was attributed to "bad medicine" administered by Captain Dominis of the brig Owyhee, which had been trading in the river.
The first white man to settle on Scappoose Plain was James Bates, an American sailor, who probably deserted from the Owyhee in 1829. The town of Scappoose had a slow growth and was not incorporated until July 13, 1921. In 1934 fire destroyed several buildings. Today it is a trading center for a prosperous farming community with large potato warehouses and a pickle factory. ..."
