CMBR is Growing!

Help us grow beyond Mirror Lake!

CMBR has grant funding for 2023, but needs your matching donations! Every dollar you donate turns into TEN dollars towards the trails and our MTB community. Our goal is to raise $40k.

Please renew your memberships, and don’t forget to PICK-CLICK-GIVE!

In addition to our regular Mirror Lake trail work, CMBR volunteers are now grooming Briggs Bridge and Lower Eagle River Trails in Chugach State Park! We are working with Parks and Rec to build new trails in Beach Lake Park this summer, and we have plans to continue trail improvements at the Mirror Lake Singletrack. Wow!

Your donations make this happen. Thank you.

Merry Masher 2022 Course Options

We are working on two options for the Mirror Lake Merry Masher.

First option is a snowmachine-groomed course, using multiuse trails and a loop on Edmonds Lake. This course will depend on how much overflow is on Edmonds:

Merry Masher 2022 Machine Groom Option here:

The second route is our more-traditional winter XC-style race on snowshoe and snowdog-packed singletrack. We’ll add in these sections if you all can get them packed down. Priority goes to Easy Peasy, Hot Tamale and Raven’s Ridge.

Merry Masher Singletrack Option here:

If it all comes togther we might be able to run both courses together on a longer loop. Our goal is a 6-mile short course and 12-mile long course.

Beach Lake Trail – Alternative I (revised)

Representatives from the Chugiak-Eagle River Parks and Rec Board of Supervisors, Chugach Mountain Bike Riders, and the Chugiak Dog Mushers Association stomped around the woods together on Sunday, Nov 20th, in an effort to better understand the needs, wants, and concerns of each user group.

Alternative I (revised), a “Single Bridge” on the portage trail between Beach Lake and the inlet was proposed. This alternative will solve the existing conflict between off-leash dogs and mushers on the Portage Trail (between Beach Lake and the Inlet,) and there will be no loss of mushing trail mileage. It will provide a direct ADA-accessible route to the inlet.

Each group will bring this back to their boards for discussion and further modifications may be made. We are hopeful that this alternative is one that can work for all the interested stakeholders.

Other alternatives may still be considered. Please email for more information.

Beach Lake Trail Additional Alternatives E & F.

Mushing Only Sign at Beach Lake Park

Connecting Eagle River to the Coast

Chugach Mountain Bike Riders is working with Chugiak-Eagle River Parks and Rec to develop a cost-effective design to bring hikers-bikers-dog walkers-skijorers and other non-motorized users around the west side of Beach Lake to the Knik Arm of Cook Inlet.

We are tasked with protecting the existing dog mushing opportunities, while offering an ADA-accessible trail that will be supported by our fiscally conservative community.

The original proposal can be seen at

Alternative F keeps all existing mushing trails.

Alternative F: Two Crossing Solution.

Keep all the mushing trail corridors, but move the inner mushing trail away from the lake edge, then add a multiuse trail 25′ back from the lake.  Build a new mushing connection 250′ away from the portage trail between the lake and inlet. Install fencing and gates (or chicanes) to stop casual crossing of the mushing trails.

This Alternative does not give the preferred 100′ separation between uses, and is not a grade separated crossing, but should satisfy all other goals within the grant funding available.

No Changes to Existing Trail Corridors. Upgrade narrow hiking trails to ADA standards

Alternative G: Summer-Only ADA Coastal Access

Upgrade existing social hiking trails to ADA standards

Beach Lake Lodge at the south end of Beach Lake provides barrier-free recreation to ADA standards. The current ADA multiuse trail ends after 1/4 mile where the proposed winter gate is shown on the map.

The mushing trails are open to multiuse in the summer, and while hikers can access the inlet and this trail system through a spider-web of skinny social trails (or bushwhacking through the forest), the inlet is not accessible from the ADA parking lot.

This is a minimal build alternative that does not alter any mushing trail routes, but upgrades existing social hiking trails to ADA standards.
