Exhibit K - Climate
The subject area is at the western edge of the plains near the
foothills. In this area there are several variations of climate relative
to that of the eastern plains. The average wind movement is comparatively
less, but due to the site's location near the foothills, it is subject to
periodic turbulent winds as a result of the mountain wave effect. Relative
diurnal temperature changes are not as great; summer temperatures are lower
and winter temperatures higher. Precipitation is also relatively less as a
result of the rain shadow effect. The decrease in overall temperature is
less than expected despite the gains in elevation from areas on the plains
to the east. This occurs because of local mountain and valley winds below
the Royal Gorge where frequent descending air masses prevent inversions
necessary for the accumulation of excessive cold. This tends to produce a
milder winter climate than most elsewhere in the state.
Climatic data for the town of Canon City (elev. 5,332 ft.), located
about 5.1 miles to the northwest of the pit site, is provided here. Much
of the data was derived from various National Oceanic and Atmospheric
Administration publications which compile data from a recording station
located at Canon City Other climatic data was obtained from Climates of
the States, Colorado, by Joseph Berry, U>S> Department of Commerce,
Climatography of the United States, No. 60-5.
The mean annual temperature for Canon City is about 54.8°F. The mean
minimum January temperature is about 20 °F.; the mean maximum January
temperature stands at about 46°F. In July, the mean minimum temperature is
about 61°F and the mean maximum temperature is about 90°F. The seasonal
temperature ranges from about 100°F to a low of zero to -10°F or -15°F.
