He acquired
Beacon Rock in order to preserve it from demolition, and built the trail to its peak; his children donated it, and nearby Hamilton Mountain, to the state after his death. Biddle Butte, also known as Mount Zion, in Skamania County is named for him, and as an early automobile enthusiast in the area he was known for driving to its summit, and for scouting the early automobile roads of the region. He had two children, Rebecca Baird Biddle (1888-1950) and Spencer Biddle (1890-1961). Spencer enlisted in the
Spruce Production Division in 1918. Rebecca married Erskine Wood, son of famed Oregon writer
Charles Erskine Scott Wood. Rebecca and Spencer deeded the property, along with Hamilton Mountain, to the State of Washington in 1935 with the stipulation that it must be a public park. Henry died in 1928 on a hunting expedition with Spencer in southern Oregon near Lakeview. He was to be interred in Portland, Oregon. Following his death, his estate was valued at $670,000 (), the largest amount filed leading up to the time in
Clark County, Washington. His wife Helene died the following year. == See also ==
