CRYSTAL PIT faults produced huge displacements in older, equally large faults. • This has resulted in some of the most complex geological structure found in Colorado. Although occasional small earthquakes are detected in these huge fault systems, seismic activity is presently very low. It is apparent that millions of years ago the Pikes Peak region may have been one of the most seismically active areas in the Western United States. Today, the Pikes Peak Highway extends along its sinuous route to the top of the famed peak. This gravel pit site, although only a few hundred feet north of the highwayycannot be seen from any location L along the highway. A low ridge and dense forests on the north side of the highway completely separate the pit area from the highway. One small power line extends across the location where the pit entrance to the west phase will be located under a portion of the pit. Another small line extends across the east phase. The power lines will not be adversely affected by the operations as work will avoid the lines. Other than these two features, there are no valuable, man made • structures within 200 feet of the pit limit. Therefore, the pit should not have any significant effect on any man made structures in the area. CLIMATIC INFORMATION The climate of this site is largely unknown in precise detail due to a lack of weather stations in the immediate area. The average annual temperature is probably about 35 degrees F. with maximum summer temperatures of probably about 90 degrees F. and minimum winter temperatures of about zero degrees F. with extremes to about -25 to -35 degrees F. in winter and 100 degrees F. in summer. Wind is probably not a highly significant factor on either phase, but there is clear evidence in the growth forms of trees that wind can be very significant on high points in the surrounding areas.
