In 1841 Charles Wilkes of the U.S. Exploring Expedition called the point "Katalamet Head".

"... Katalamet Head is a high and remarkable bluff, which may be seen from the coast: it borders the river, and is the most northern point of the hills which stretch to the south. ..." [Wilkes, Chapter XVI]

In 1870 land records on the Bureau of Land Management Website (February 2006) show Robert E. Aldrich being granted title to 30.7 acres, for property in T9N R7W Sec.21, Lot 2 or "West Half of SE Quarter".

The 1875 and 1890 U.S. Coast and Geodetic Survey Chart "Columbia River Sheet No.2" have the point as "Cathlamet Pt.".

The 1948 U.S. Coast and Geodetic Survey Chart #6152 "Columbia River, Harrington Point to Crims Island" has "Aldrich Pt.".

"... Cathlamet Point -- This is the high point on the south side of the river, one and nine-tenths miles south thirty-one degrees east (S.31^o E.) from Three Tree Point. The point is the northwest termination of a rocky spur which projects more than two miles beyond the general margin of the basaltic formation. It reaches an elevation of four hundred and fifty feet only one-quarter of a mile back from the point, and gradually increases to over one thousand feet. It is densely wooded. It is here where the river has its narrowest regimen between the basaltic walls of the canyon-like valley. Part of this width is occupied by low, marshy islets in part wooded, in part having such gentle slopes that the shore-line can not be well defined. The main channel runs close under the north shore; and a channel carrying less than six feet of water runs close under Cathlamet Point. ...

When Broughton, in 1792, made the first examination of the river from the mouth to Point Vancouver, above the mouth of the Willamette, he considered the lower part, from Cape Disappointment ot two or three miles east of Cathlemet and Tree Tree Points, an estuary to the mouth of the river proper. He says: 'The two points of entrance into the river are formed by low, marshy land, the southernmost seemed to be an island; and to the NW. of the northern, a branch took a northerly direction, which was Orchard's River.' This river is now named the Skumaquea Creek, and the low land opposite is Welch's Island and Tenasillahee Island. ..."
