Biographical / Historical

The Citizens for Glenwood Canyon Scenic Corridor advocacy group was created in 1974 by Colorado citizens interested in finding the best possible transportation solution for the Glenwood Canyon I-70 corridor. The organization was headed by director Mark A.A. Skrotzki and honorary directors included singer-songwriter John Denver and former U.S. Secretary of the Interior Stewart Udall. The group advocated against the construction of a four-lane I-70 highway through Glenwood Canyon. Instead, they petitioned for Glenwood Canyon to be designated as a "scenic corridor," versus a "transportation corridor," and for a two-lane road to be built. Former Secretary of the Interior Stewart Udall also supported the organization. While the organization did not win their lawsuit, their advocacy efforts resulted in more attention to conservation during construction, such as the creation of the Supplementary Environmental Impact Statement (SEIS) and a change in Glenwood Canyon’s designation from “transportation corridor” to “scenic corridor” in 1975.
