Ironwood Forest Management Plan – MTB’s Could Lose – Write Now!

You may have seen notice of the proposed management plan for the Ironwood Forest, comments due 9/2. This plan would limit bicycle use to existing doubletrack roads exclusively! It would have the effect of excluding 90 miles of beautiful single track within the Ironwood National Monument and sets a bad precedence for mountain biking in southern AZ. SDMB has led rides out there over the years since our inception, bike packers love the solitude and the possibilities for exploration, and it is a unique place where human powered quiet recreation opportunities are appropriate to enjoy the land with minimal impact to it or the floura or fauna. And it help mitigate issues relating to illegal motorized use, northerly migration, trafficking, dumping, etc…

Here is some background from the document. For information on Trails, check out page 11 of the NEPA document. The only mention of bicycles is on page 24:

Non-mechanized Non-motorized Uses 3.13
Monument roads, primitive roads, and administrative roads are available for non-mechanized non-motorized use, including foot, horse and mountain bicycle. Livestock and human-pulled wagons and carts may also be used on these routes provided that the route is physically suitable for passage without improvement or causing damage to Monument objects. Use of non-motorized mechanized methods of transport (bicycles, wagons) is prohibited on non-motorized trails.

Future of Redington Pass Community Stakeholder Meeting – Monday, April 28th – 7-9:00pm.

Please join us and the Friends of Redington Pass (FRP) next Monday, April 28th, 7:00-9:00 PM, for a community meeting on the future of Redington Pass. We would like to get a good turnout from all the users in the Pass and we need your support to represent mountain bicyclists interests adequately!!!

The purpose of this first meeting is to get input from everyone interested in the Pass. FRP is developing a Collaborative Area Management Plan proposal to submit to the Forest Service with recommendations on how to improve management of the Pass. We have been working with them to focus on what people enjoy doing now in the Pass, areas where there are concerns, and what they would like to see in the future. Participants will be locating special areas and areas of concern on sets of maps we are preparing for the meeting. We will also be reaching out over the summer and early fall to attend others’ group meetings to gather more input. In addition, FRP will also be creating a space on our website for people to provide input on line.

Please note that the meeting location is in the Lew Sorenson Community Center at the Emily Gray School (east side). For more information, visit the FRP website.

Last Saturday Ride – Arizona Trail Day! – March 29th

Please join our Last Saturday Ride in coordination with the Arizona Trail Day- Tucson and the Colossal Campout. We will be meeting at 8:30 AM at the Pistol Hill Road trailhead (at the kiosk just South of Old Spanish Trail). We will do an out and back to Camino Loma Alta, including the newly opened (to mountain bikes) Hope Camp Trail. We will then keep going past Pistol Hill Road to Colossal Cave park to participate in the AZ Trail Day festivities, and folks can ride back to Pistol Hill Rd. at their leisure, or as a group.

Please RSVP here on Eventbright.

The out and back to Camino Loma Alta totals 14 miles, and the out and back to Colossal Cave will total about another 9 miles, for a total of roughly 23 miles with maybe 2000 feet of climbing. The trail is rolling and non-technical. We will move at a relaxed pace, and no one will get dropped. If folks don’t want to do the whole thing they can turn around at any point, and there will be the option to drive from Pistol Hill to the park rather than riding on singletrack.

Pistol Hill Rd. to Camino Loma Alta trail information.

In the evening, the Arizona Trail Association is hosting the Colossal Campout at La Sevilla Campground at Colossal Cave. Join us for live music, food from It’s Greek to Me and Arizona Trail Ale by the campfire.

This event is part of Sirena’s 800-mile Arizona Trail Trek to promote the Arizona National Scenic Trail, the Gateway Communities, and the new official guidebook. More details on the AZT Trek can be found at

Donations are greatly appreciated and go toward Sirena’s goal of raising $20,000 to protect, promote and maintain the Arizona National Scenic Trail!

Trail Love Day – Bug Springs – April 5

We will be working on Bug Springs Trail, doing some tread maintenance below the hoodoos. Meet at Le Buzz at 7:30AM, or the lower Bugs trailhead at 8:00. Plan on working until noon.
