middle to lower portions of the landslide deposit. The more common features are cracks 3 to 12 inches in width. Cracks can be traced for lengths in excess of 100 feet. Most cracks evidence translational offsets indicative of downslope and lateral movements. Cracks occur along contour, parallel to the fall line, and at random orientation. No discrete conclusions could be made about the actual depth of the basal failure plane of the landslide mass(es). The observed features are typical of large landslide masses in the Williams Fork formation. These landslides occur prolifically throughout the North Fork Valley on slopes of varying gradient and aspect. The largest and most notorious active landslide in the area is the Muddy Creek Landslide, east of Paonia Reservoir. The immediate area of the rejuvenated landslide movement is grossly headed by the large (up to 50' vertical relief) headscarp mapped by Dames and Moore in their 1993 report. The active landslide mass appears to be approximately 1,600 in length between approximately the 7450-foot and 7150-foot elevation contours. While numerous extensional cracks were examined, DMG did not discern a major compressional zone, but inspection logistics did not allow examination of the lower third of the landslide where one would expect compressional features to predominate. Norm Every of MCC, who has examined this area recently, did not recollect a significant compressional or overrun area. Translation of the sliding debris can be accommodated in general bulging of the landslide mass, which is normally evidenced by cracking parallel to the fall line. Many such cracks do exist on the active landslide mass. Commonly, the specific translocation of landslide material can only be determined by the comparison of precision pre-failure versus post- failure surveys of the landslide mass. In the opinion of Dr. Pendleton, the cracking and disruption which we examined in the SWl/4 of Section 24 on Jumbo Mountain is indicative of a 30 to 50 acre landslide mass. This landslide exhibits characteristics common to modern landslides throughout the North Fork valley. As such we would expect this landslide to undergo several years of active creep, after which it may become more stable. The cracks and troughs affecting roads and trails will require grading to render them passable. Cracks in the off-road areas will close by in-filling and features will become more subdued with erosion. The DMG recommends road repair be more extensive than just filling the crack. If a four or five foot pad of ripped and recompacted material is placed across the major features it will increase the capability of accommodating the continued creep movements which will normally occur for the next several years. Some larger cracks and troughs will undoubtedly required repeated treatment to maintain trafficability. These repairs should restore safe access to the affected area, which may be important for emergency situations on the Mautz's Chipeta Guest Ranch. Continued monitoring should be periodically conducted to determine if additional repairs are required. Signage should be erected to inform users of possible hazards. Recurrence of Jumbo Mountain Landslide Activity DMG's examination of the landslide discerned evidence of recurrent modern (since white man's occupation) activity. In several areas, predominantly in the middle to higher portion of the landslide mass, closed extensional troughs are present. These undrained grabens are caused by downslope movement of landslides pulling away from the upslope headscarps. The most 2
