Grave Island Memorial & Overlook
Above, old post holes at the overlook. I suspect that the overlook here was a little more of a big deal back in the day when they were building the dam and the highway was still on Seufert Viaduct (I think it still was then), and while it might not have been the Bonneville Overlook, it was a little more developed than it is now. That is something that is definitely calling for some more research.

One big problem created by the second dam was that Memaloose Island (literally "Island of the Dead" in Chinook trade jargon), a sacred, ancient Indian burial ground, would be submerged. There was but one solution to the problem, since the government was determined to have its dam. The ancient remains were unearthed as much as possible prior to allowing the reservoir to fill, and reburied nearby.
