The Town of Mammoth Lakes Trail System Master Plan, Sherwins Area Recreation Plan and Sherwins Working Group provide a blue print and specific trail concepts for implementation by the Measure R Trails Program, aka the Mammoth Lakes Trail System (MLTS). Several specific concepts have been constructed in recent years such as SHARP ID #13 (the Mammoth Rock Trail Connector) and SHARP ID # 18 (the Meadow Trail Connector). These trails were constructed using skilled Town Trail Crew and Cal Fire crews with hand tools in 2018. 

For the next phase of work in the Sherwins Area, the Inyo National Forest Supervisor provided direction to USFS staff to work with The Town of Mammoth Lakes to develop a project building on important community driven planning efforts that will work well for the landscape and for the community.

The next phase of trail projects that is formally submitted to the Mammoth District includes SHARP ID #29 (Solitude Canyon) from the Sherwins Area Recreation Plan and several concepts from the Lakes Basin Special Study 2011. The Solitude Canyon concept connects from the Mammoth Rock Trail and winds up through Solitude Canyon and over the Sherwin Ridge into the Lakes Basin. The concepts from the Lakes Basin Special Study will connect Twin Lakes with Lake Mamie and Horseshoe Lake to give trail users a way to get from each lake on a sustainable system trail facility.

The trail corridors described above will require more analysis and design adjustments before formal scoping will occur for a final focused environmental review. This concept and others were included in the Town of Mammoth Lakes Programmatic EIR for the Trail System Master Plan. The next phase of work requires a discrete NEPA review and we are now working with Inyo NF staff to develop the Proposed Action.

Future phases of work will include remaining concepts from the Sherwins Area Recreation Plan and Lakes Basin Special Study as they become feasible for the Town of Mammoth Lakes and the Mammoth District of Inyo National Forest.
