ANGEL TERRACE
At the bottom of the hill on the left are the ruins of Angel Terrace. Visitors during the 1920’s and 30’s saw it as a beautiful algae-tinted feature. Today it is beginning to crumble and young pioneer plants are taking root in the thin soil over its surface.
Alteration and change are constantly occurring in the thermal basins and add to the mystery of this fascinating land. They bring not destruction and loss, but rather new birth and gain. Who knows what interesting ornate new features may develop by next year, or in five years. You are encouraged to return again and again to enjoy this ever-changing scene.
For your safety and the protection of the fragile features, PLEASE STAY ON THE TRAILS. Pets are not permitted on the trails, for their protection and yours.
