Baseline Information for Point 52-8 is derived from events beginning on 6/'10/19981hrough 9/24/7999, a pedad of -16 months. Point influenced by mining on 924/1999.
The monitoring point location for 52-8 (Spnn9 2-8) is located along the upper edge of the Freeman Gulch Roatl as it originates from the Hubbartl Creek road. Its Oow
originates from the exposed sandstone outcrop located high above the Hubhard Creek Canyon along the eastern racing walls of the cliffs 6elween the valley created by the
Nonh Fork of the Gunnison and Freeman Gulch.
