Roaring Fork Gorge Management Plan Table of Contents III 1. INTRODUCTION 1.1 Purpose The Roaring Fork Gorge has been a special place to residents and visitors of Pitkin County for well over a century. The planning area is comprised of eight different public properties, two fishing easements, two conservation easements and a trail easement. The public enjoyment of this area started in 1969, with the Denver and Western Rio Grande Railroad right of way being Planning Area Map is located in Appendix A given to the County and it continues to expand, most recently with the addi- tion of the Gold Butte property. The terrain varies greatly, from the bottom of the river gorge to the sage flats and shale slopes above. With that comes a diversity of vegetation, habitats, geologic features and user experiences. The gorge is also a key wildlife corridor, linking Sky Mountain Park to the Roaring Fork River, Red Mountain and Woody Creek Drainage. Every year more and more recreational users are drawn to the Gorge’s unique amenities. Over 1,000 people are expected to reside in the commu- nities currently connected to the Gorge, via the Stein Trail, with in the next decade. With each season we continue to see the user numbers increase and requests for the use of the resources continue to evolve. Six of the eight gorge properties have never had a management plan to guide their future. The purpose of the Roaring Fork Gorge Management Plan is to embrace the strong public history, diversity of uses, habitats and experiences and create a comprehensive guide for the future. We began by taking an inventory of all the existing conditions and hosting a series of public meetings to un- derstand the users’ needs. We then evaluated all we had learned looking at the opportunities, constraints, existing issues and public comments. Using this information we developed a draft plan, including management actions for the future of the gorge. The draft plan was out for 2 months of public comment and we revied and listened to all we recievd. Staff then revised the draft plan, based on the comments received, to develop the final plan. 1.2 History of the Roaring Fork Gorge View of the Gorge in 1887 View of the Gorge today Roaring Fork Gorge Management Plan Page 1 Historic image of flume from 1900 Flume location today The Roaring Fork River descends out of Aspen, Colorado through a narrow gorge cleft between buttes of red and gold. The canyon was spared from development due to its dramatic geology. Over the last several million years, the Sawatch range has risen some 26,000 feet up a major fault line across the mouth of the canyon, which has literally flipped Red Butte onto its back. The oldest rocks lie on the top of Red Butte, creating a geologic anomaly. Human history within the gorge is marked most significantly by the former grade of the Aspen Branch of the Denver and Rio Grande Railroad. This route was hastily carved into the canyon during the great race with the Midland to be first into Aspen in 1887. The Rio Grande had reached Carbondale on October 13 of that year, as the Midland was still fighting its way over Hagerman Pass. With astonishing speed, the Rio Grande RR laid track up our valley and through the gorge, reaching Aspen by October 27, 1887. The entire town of Aspen turned out to meet the first train, while a local brewery took a wagonload of beer to the workers.
