The Logan Pass Visitor Center was one of the most significant Mission 66 projects, involving the construction of a large visitor orientation facility with attendant parking lots, utility services and amenities at the summit of Logan Pass. The altitude of the pass is , and is inaccessible from October to May in most years. The summit of Logan Pass had previously been used as a rest stop with toilet facilities. The size of the visitor center was somewhat reduced because the Saint Mary Visitor Center at the east end of the Going-to-the-Sun Road and the park headquarters at the opposite end at West Glacier provided appropriate orientation features in a less demanding physical environment.
