Stub Stewart Memorial State Park has been a favorite astronomy spot for amateur astronomers in the area, with organizations such as OMSI hosting multiple star parties at the venue.

[3] The site is a great spot for astronomers to set up their telescopes and view the night sky as the trees shield the hilltop from the light pollution from the cities in the area.

In 2005, it was changed to the current name which honors the memory of lumberman and state representative Loren LaSells "Stub" Stewart, who had died in January of that year.

He had served an extended time on the Oregon Parks and Recreation Commission, the co-owner of lumber company and a noted philanthropist.

Because of his contributions, Pihl had a scenic viewpoint named in his honor called "Hollie's Point of View", a double entendre for those who knew him, as he was a very opinionated man.

[7] The built environment includes several vehicular bridges, a visitor center, cabins, day use areas, and horse camp.
