clear that a considerable force caused it. No apparent impact damage could be found <br />on the tree as if a large rock had hit the tree. Furthermore, it was apparent that <br />• no rocks from the mining operation came down into this area as no dam:~ge to the <br />uphill soils or vegetation could be detected at this time. As further evidence, the <br />last time any mining was done which could have produced this damage w:as at least two <br />years ago. This tree had been broken by something much more recently than that, as <br />the needles on the tree were still present although brown and dry. Little needle <br />fall had occurred. It therefore appears this tree had been damage by something <br />during the last 6 to 30 months and it is highly unlikely this loss occurred as a <br />result of anything related to the mining operation. <br />ASSESSIIVT ~ DAMfiC-ES: It is apparent that a number of rocks were pushed over the <br />side of Phase 1 sometime between 14 to 22 months ago. It does not ap{year that any <br />rocks were pushed into the canyon more recently than that time period„ Some amount <br />of the rock present in the bottom of the drainage originated either from natural <br />rockfall or from mining in the 1930's or earlier. <br />It is likely that this spillage, which also placed a large amount of rock on <br />the slope immediately below the mining area, occurred as a result of :~ dozer <br />operator who was fired as a result of an inability to move rock within the quarry <br />• according to instructions. The date of this problem with the equipment operator <br />corresponds with the approximate date of the spillage. <br />DLRATION ~ SPILLAGE EVENT: It is unlikely, based upon the amaant of rock in <br />place, the duration of the event took more than about 1 to 3 days, anti it is most <br />likely it occurred over about 1 or 2 days. Vegetation indicators shay that all the <br />damage was caused at very nearly the same time. Furthermore, the period during <br />~.hich the equipment operator was working the edge of Phase 1, was detracted pushing <br />rock improperly, and was subsequently released from his duties was a matter of just <br />a few days. Therefore, Castle Concrete feels the duration of the event was between <br />1 and 3 days. <br />RDCK QV CAVE ~ TFE WINDS PROPERTY: A letter from Grant Carey, manager of The <br />Cave of the Winds, is provided in this document. This letter indicates that htr. <br />Carey is aware of the rock on Cave of the Winds property but is not crxx erned about <br />it as a trespass or danger to his operations. It should be noted tha+: the bottom of <br />the canym near the Road is heavily posted with signs indicating no hiking, climbing <br />• <br />CORRECTIVE ACTION PLAN SIV1'DE}2 ROCK SPILLS PAG£ 4 <br />
