The town of Mosier was founded by Jonah H. Mosier, a Missouri builder who came to Oregon in 1853. He filed a donation land claim for 640 acres at the mouth of what is now Mosier Creek. He built a water-powered sawmill, the Mosier Inn, and a blacksmith shop. The first post office was established on December 31, 1884 and the town was platted in 1891, although the plat was not filed in county records until 1909. Today Mosier is the third largest city in Wasco County.

Tom McCall Preserve at Rowena, (Drive Hwy 30 east from Mosier for seven miles and park at the Rowena Crest viewpoint), . Managed by the Nature Conservancy, this 270-acre preserve is best visited in May when wildflowers carpet the plateau. A short trail meanders across the plateau on the north side of the highway, and a tougher trail climbs 1.8 miles up to McCall Point. Dogs, horses and bicycles are not allowed on the trails. Picking flowers, camping, and off-trail hiking are also not allowed. Beware of ticks and poison oak, both of which flourish here.edit
