<br />• ~ 3.0 RESIILTS AND DISCCSSION <br />3.1 1978 Climatic Pattern at the Mt. Gunnison Mine <br />3.1.1 Precipitation and Soil Moisture <br />The spring and summer of 1978 vas characterized by abundant early <br />spring precipitation followed by very dry conditions during the late <br />apriag and summer. Precipitation data collected from just east of Bear <br />_. Mine were analyzed for precipitation amount and frequency. These data <br />are presented in Appendix A. <br />Between March 1 and May 31, 3.93 inches of precipitation were <br />recorded on the site. Precipitation amounts were equal to or exceeded <br />.20 inches on eight days: March 1, March 2, March 3, April 1, April 2, <br />April 9, April 29, and May 21. These data indicate that abundant soil <br />~~ moisture vas present during the early part of the growing season. <br />The precipitation pattern changed markedly sear the cad of May. <br />Only .69 inches of rainfall were recorded between May 31 and August 31. <br />' Only one daq (June 29) experienced precipitation of .10 or more, indicating <br />that precipitation vas sparse and generally ineffective in aiding plant <br />;_ growth. There were several long intervals when no measureable rainfall <br />vas recorded: June 7 - June 27 (20 days), Juae 29 - July 10 (11 days), <br />- July 17 - July 29 (12 days), and August 24 - September 20 (27 days). <br />The sparse and infrequent rainfall during the warmest part of the year <br />indicates that planted seedlings suffered varying amounts of drought <br />etrees. <br />From September 1 to October 19, .59 inches of precipitation were <br />~~ recorded. Maximum daily precipitation (. 37) was recorded on September 28. <br />19 <br />
