Red Rock Pass consisted of loose sand and gravel. Escaping water washed away this material, deepening the channel and causing the water overflow to increase rapidly. The flow of water through the pass is estimated to have been three or four times the amount of water flowing through today's Amazon River. Red Rock Pass continued to erode for about 25 years until the water reached a layer of resistant limestone, and the lake stabilized at the Provo level, about 400 feet lower. ===
