1. Memaloose -- Island of the Dead Marker
Captions: (bottom left) The lone monument on Memaloose Island marks the grave of Victor Trevitt, a pioneer printer, businessman, state legislator, and friend of the Indians. Trevitt requested burial here among the people he loved. Ironically, water rising behind the Bonneville Dam prompted relocation of Indian graves during the 1930's, but Victor Trevitt's grave remains.; (upper right) Burial canoe; (background) Memaloose Island is one of several "islands of the dead" once found in the Columbia River. Many of these islands are today covered by the backwaters of Columbia's dams -- only one-third of this island seen by Lewis and Clark is visible above the river today.
Inscription.
Until very recent times, the Indian people of the Columbia River did not bury their dead, Instead, bodies were wrapped in robes or tule mats and deposited in canoes that were placed in the woods, on rocky points, or in cedar vaults on islands like Memaloose. The name Memaloose is derived from the Chinook word memalust, which means "to die."

The Corps of Discovery, under the command of Meriwether Lewis and William Clark, passed this island in their quest to reach the Pacific Ocean on 29 October 1805—they called it "Sepulcher Island" (burial island). On their homeward journey, the explorers visited the island on 15 April 1806, and Lewis noted, "thirteen sepulchers on its rock which stands near the center of the river and has a surface of about 2 acres above high water mark."
