Otto broke several trails on the Monument, brought in elk and bison herds (both left the park), and served as the primary mouthpiece, promoter, and fundraiser for the area. With his persistence, the area west of Grand Junction and east of Fruita became a national monument in 1911, with Otto serving as the first park ranger for the monument. yes yes https://www.nps.gov/colm/index.htmNational Park Service page for the Colorado National Monumenthttps://en.wikipedia.org/wiki/Colorado_National_MonumentWikipedia entry for the Colorado National Monument
