CLIMATE INFORMATION <br />Exhibit K <br />Climate Information <br />The climate of this site is considered inland continental mountainous. Although it is not in <br />the high mountains it is nevertheless a mountainous location. The location on the south side of Pikes <br />Peak places it on the principle orographic precipitation side of that mountain mass. Thus it receives <br />reliable precipitation. Because the site is well elevated above the Arkansas River Valley (about 2800 <br />feet) it is within the upper reaches of the orographic upslope flow from the south. The site is <br />essentially a mountain top and although about 6000 feet lower than Pikes Peak, is exposed and <br />therefore subject to strong wind influences. <br />There are no climatic records from this site other than the impressions provided by people <br />who have experience in this area. Therefore data regarding precipitation, temperature, wind, and <br />other climatic parameters are completely lacking. Three sites can provide a picture of the climatic <br />patterns for the site, but are little help in estimating actual values for climatic parameters. <br />Following is a presentation of the key data from these three sites. They are Colorado Springs, <br />Pueblo, and Canon City. Colorado Springs probably provides the closest picture of the climatic <br />conditions on this site, but even that is little more than a rough approximation. That location is on <br />the east side of Pikes Peak and at slightly lower elevation. Therefore climatic parameters there are <br />probably different from this site, but the overall patterns are probably similar. Pueblo, located <br />many miles southeast of this site, deviates even more with respect to conditions, but can provide <br />additional clues to patterns. Canon City, located southwest of the site, is somewhat more <br />representative than Pueblo, but still deviates considerably, From the data presented below this <br />exhibit will conclude with a projection of what the climate on this site is probably like. <br />Temperature <br />Figures 1 and 2 presented below show the temperature patterns on a combined average <br />monthly basis for each of the three record sites, Colorado Springs, Pueblo, and Canon City. Figure <br />1 presents the Mean Daily Maximum Temperature for each of the sites for each month. Figure 2 <br />presents the Mean Daily Minimum Temperature. Colorado Springs and Pueblo follow very similar <br />patterns in summer, although Pueblo is significantly warmer. In winter, Pueblo tends to be colder at <br />night than Colorado Springs, but warmer during the day. This undoubtedly is due to cold air <br />drainage down the Arkansas River Valley. <br />Canon City exhibits a rather different pattern. In summer, it is quite similar to Pueblo with <br />respect to minima, but cooler than Pueblo during the day. In winter, it is significantly warmer <br />during both day and night than Pueblo or Colorado Springs. This is probably due to its close <br />proximity to the mountain front and downslope wind flow. Pueblo and Colorado Springs are both <br />more exposed to colder air from the east. <br />Table Mountain Quarry -Castle Concrete Company Exhibit K (Amendment 1) Page 1 <br />
