<br />Memo to Berry/Boulay <br />Jumbo Mountain Landsliding <br />page 5 <br />occurrence of landsliding and of its implications for use of the <br />affected lands. In seventeen years of examining landslides <br />throughout the valley I have never discovered, or been informed of, <br />a fatality or injury to an elk, deer or cow in or near any <br />landslide. The wildlife and domesticated cattle are apparently <br />capable of surviving in close proximity to the cracks and troughs <br />indicative of landslides. Landsliding is capable of effecting <br />almost any slope in the valley on a random basis. <br />Landslides are a constant nuisance to land owners in the North Fork <br />valley. Landowners have learned to live with the interruption, <br />inconvenience, and expense caused by landslide occurrence. State <br />Highways, private roads, railroads, fish hatcheries, bridges, <br />irrigation facilities, commercial buildings, and private residences <br />have all been impacted by landsliding. Local residents know that <br />care must be exercised when traveling within landslide terrain, <br />because the cracks and troughs represent a potential hazard to <br />health and safety. <br />Mautz Guest Ranch Cabin <br />Subsequent to the approval of the MCC permit revision to conduct <br />mining of the 'B' seam beneath Jumbo Mountain, Mr. Mautz erected a <br />guest ranch cabin above the gate roads between Panel 8 and Panel 9. <br />This location had been predicted to experience potentially damaging <br />subsidence within the approved permit documents. That cabin <br />subsequently experienced subsidence and exhibited minor damage. <br />Damage included minor cracking of reinforced foundational grade <br />beam footings, separation of the slab-on-grade structural floor <br />poured within the grade beam foundational footings, pinching of <br />doors, and drywall cracking and drywall tape separation. It does <br />not appear that major structural damage has occurred. <br />Mr. Mautz informed the Division and MCC of the damage. Following <br />inspection of the structure, MCC proposed and completed repairs to <br />the structure, with Mr. Mautz's approval. MCC has subsequently <br />proposed to compensate Mr. Mautz for diminution of the structure's <br />value or to conduct additional minor subsidence-related repairs. <br />To the best of my knowledge, Mr. Mautz has refused MCC's proposal. <br />Conclusions <br />My examination of the active landslide within Section 24 on Jumbo <br />Mountain, and my review of the conditions attendant to that <br />situation, lead me to the following conclusions. <br />(1) A 30 to 50 acre active landslide is occurring within the SW1/4 <br />of Section 24 on Jumbo Mountain, above and adjacent to <br />
