In Middle Park boiling springs issue from depths below and gather in pools covered with con-fervae. Leaving Middle Park the river goes through a great range known as the Gore's Pass Mountains; and still it flows on toward the Colorado, now through canyon and now through valley, until the last forty miles of its course it finds its way through a beautiful gorge known as Grand River Canyon.
