The primary focus of the bill is to allow Fort Clatsop National Memorial, across the Astoria Bridge in Warrenton, Ore., to expand to 1,500 acres from its current size of 130 acres. The park service is reportedly considering acquisition of the Station Camp land as part of that expansion.

The impetus for the bill sponsored by Sens. Ron Wyden, D-Ore., and Gordon Smith, R-Ore., is to expand the national memorial by 2003, when one of the most important events of the American West - the bicentennial of the Corps of Discovery - gets underway. Park service officials have been working on a deal with Willamette Industries and other Fort Clatsop landowners to acquire more property once the bill is passed.

Fort Clatsop, a national memorial near the site where the explorers spent the winter of 1805-06, is already considered a major draw in the upcoming bicentennial commemorations. Washington historians say Station Camp in McGowan, Wash., is in fact the end of the trail, as it was the first resting point for the Corps of Discovery, which was charged by President Thomas Jefferson with charting the West to the Pacific Ocean.
