motorized traffic, including motorcycles. Two railroad tunnels on Rollins Pass are completely caved-in: Tunnel #31 (the tunnel at Ladora) and Tunnel #33 (the Loop Tunnel at Riflesight Notch). Closures also include sections leading to Tunnel #32, Needle's Eye Tunnel—a high-altitude railroad tunnel constructed in 1903 and used through 1928. Surveyors looking to establish the automobile route over the pass in 1949 found, and cleared, considerable rockfalls at the northeast portal of the tunnel. The tunnel was open to automobiles, as part of the thoroughfare over the pass, from 1956–1979 for seasonal and inessential purposes. In 1979, the tunnel was closed due to rock falls at the northeast portal; following a geologic engineering study in 1981, a Mine Safety and Health Administration study in 1985, engineering design work in 1986, and repair work in August 1987, the tunnel was re-opened in 1989. The following year, in July 1990, several thousand pounds of rock fell from the crown of the tunnel, injuring a United States Navy veteran and Denver firefighter resulting in a below-knee amputation. Since then, the tunnel was sealed by Boulder County officials along with the United States Forest Service and sizable rockfalls continue to occur at the northeast portal, southwest portal, and center of the tunnel from both the crown and shoulder of the structure. In November 1990, the post-accident engineering report, by independent geotechnical consultant Ronald E. Heuer, PhD, cited restoration errors and faulty work: design specifications were not consistently followed, rock bolts were incorrectly spaced, and gravity along with seasonal temperature variations were also listed as factors in the accident. Adopted trails Several trails on Rollins Pass are adopted.

Bush. The act amended the Colorado Wilderness Act of 1993 and designated lands within both the Arapaho National Forest and the Roosevelt National Forest as the James Peak Wilderness area and added lands to the Indian Peaks Wilderness, establishing these lands as federally protected territory. The act contained an administrative provision: If requested by one or more of the Colorado Counties of Grand, Gilpin, and Boulder, the Secretary shall provide technical assistance and
