Seismi c r1onitori ng <br />The location of the Rainbow Bridge microseismic station is currently <br />being finalized with the assistance of the USGS. With the neeessary <br />funding made available, this ageney will expedite the installation of <br />equipment as soon as it can be purchased. The equipment will be miero- <br />seismic instrument probably making use of solar energy as a power source <br />and equipped to telemeter data to Golden, Colorado, through Bureau of <br />Reel amati on microwave systems. All earth tremors or shocks that occur <br />in the immediate vicinity of Bridge Creek Canyon, regardless of the <br />source, will be reeorded. <br />9. Eeology <br />Inspeetions of the Rainbow Bridge National Monument have been made in <br />respeet to eeology. In broad concept it is reasonable to state that <br />environmentally no unantieipated changes are oecurring in the reservoir <br />slopes that are not eommon to new reservoirs. Specifieally, a light <br />, eolor change of the rock slopes is evolving from light colored mineral <br />precipitants and readjustment of sideslope sand deposits is occurring. <br /> <br />, <br /> <br />Sparse plant life or vegetation which is indigenous to the banks of the <br />creek and have been immersed for a sufficient period of time by the <br />reservoir have died. In that the reservoir and creek water have been <br />clear ~fsediments, no new sediments are observable at this time. <br />It is anticipated, however, that periodic excess runoff in flow of the <br />creek wi 11 form such deposits when it enters the reservoi r. <br /> <br />6 <br /> <br />M:;~~~1 <br />~~;:~~;i. <br /> <br />'~~j~ <br />~?i~~ <br />.~~ <br /> <br />.c. -. ,_.:~.'~. <br />. i-..-.;":;.'..-,.:" <br /> <br />'r <br /> <br />~''''M' <br />~*~~ <br />..~,-~:, <br />~,;;;!l <br /> <br />:,,;''''.>; <br />~~~j;: <br />~;1*~ <br />;1t".&",,; <br />:~~t;: <br />)*~2 <br />I <br /> <br />~:(~\~;;~~ <br /> <br />~~;? <br /> <br />t:;r:~:~~ <br />.-:,-.....:. . <br />,-_.,..:;~' ..:': <br />':::-- .:~;.:.~.; <br />~-. -,","-:;.". <br />>C.-'._" <br /> <br />......
