THE PROPOSED ACTION 1.1 INTRODUCTION This Environmental Assessment is being prepared to evaluate the impacts to the human environment of a Bureau of Land Management (BLM) proposed action to improve one trailhead to serve non‐motorized recreationists in Canaan Mountain Wilderness. The project includes: Eagle Crags Trailhead (Refer to Map 3) Expansion of current parking area to accommodate a total of ≈10 vehicles. o Current Parking Area: ≈2,200 ft² o Proposed Parking Area: ≈7,200 ft² Removal of up to ≈15 trees and multiple shrubs which comprise ≈5,000 ft² of vegetation. Installation of up to ≈350 linear feet of wooden fence to delineate parking area (with horse-friendly stepover). Rerouting of approximately 20 feet of the Eagle Crags trail Installation of gate(s) in fence to facilitate access for emergency services. Installation of a steel, four-panel information kiosk. Relocation of the existing steel trail register. Installation of one single-seat vault toilet. This project is located on public lands managed by the St. George Field Office of the Bureau of Land

  • St. George Jeepers Trail Ride Gooseberry Mesa to the "Ghost Town of Grafton", Utah 01/26/2016
    St. George Jeepers Trail Ride Gooseberry Mesa to the "Ghost Town of Grafton", Utah 01/26/2016 Another fantastic trail ride, but not without incident(s). As soon as the group left Costco and got on the interstate one Jeep developed a flat tire. We regrouped at the Apple Valley Chevron and 20 Jeeps headed out for Gooseberry Mesa. After leaving Apple Valley, we proceeded 2.2 miles east and turned north on Smithsonian Butte National Back Country Byway. After traveling 2.8 miles we turned left onto Gooseberry Mesa trail. This trip was led by Gus Peterson. Smithsonian Butte National Back Country Byway travels for 9.25 miles between Rockville, Utah, on State Route 9 and Apple Valley, Utah, on State Route 59 in southwestern Utah, just south of Zion National Park. The Back County Byway takes visitors between the Virgin River floodplain in Rockville, through the pinyon pine- juniper woodlands topping out at an elevation of 4,920, and to the sagebrush desert at the Big Plain Junction at Highway 59. Views along the way include the colorful Smithsonian Butte, Eagle Crags, and Vermilion Cliffs within the Canaan Mountain Wilderness on the east. On the west, are the deep drainages and ridges falling away from Gooseberry Mesa including Wire Mesa, Grafton Mesa, and Pastry Ridge. An added bonus is the view into Zion National Park and its towering sandstone buttes. Located on Gooseberry Mesa, at 5,200 feet elevation, is a mountain biking Mecca and a system of very popular trails. The area has the designation of "National Recreation Trail".
