when did the fire falls stop in yosemite
Yosemite Firefall The Firefall ended in January 1968, when the National Park Service ordered it to stop because the overwhelming number of visitors that it attracted trampled the meadows, and because it was not a natural event. NPS wanted to preserve the Valley, returning it to its natural state. The Glacier Point Hotel was destroyed by fire 18 months later and was not rebuilt.
Valley of Fire State Park Complex uplifting and faulting of the region, followed by extensive erosion, have created the present landscape. The rough floor and jagged walls of the park contain brilliant formations of eroded sandstone and sand dunes more than 150 million years old. Other important rock formations include limestones, shales, and conglomerates.[4]
