Here’s what we are asking you to commit to as part of the Mammoth Lakes Promise:

I will know and practice the seven principles of Leave No Trace and help make Mammoth Lakes and the areas I recreate in better for others to enjoy in the future.
I will clean up after myself and my pets (and maybe even others) by packing out all trash, including pet waste, and knowing how to properly dispose of human waste.
I will do my part to reduce waste by bringing reusable water and food containers with me and properly disposing of any trash I do create.
I will know my limitations and always be prepared so as not to put myself or others at risk for the sake of a bucket list summit or the perfect picture for the ‘gram.
I will be responsible with fire, respect local fire restrictions and ensure any fires I do make are put out completely before leaving camp
I will respect wildlife by keeping a safe distance and never feeding wildlife or leaving trash for animals to find.
I will protect the local drinking water and fisheries by recreating responsibly around waterways.
I will do my part to travel sustainably by walking, biking or riding public transportation when possible. When I do drive, I will not invent my own by parking illegally in town or pulling off the road and damaging plant life.
In winter, I will use snow chains when there are chain restrictions in place, fully clean snow off my vehicle before driving and respect the power of winter storms.
I will leave Mammoth Lakes and the Eastern Sierra better than I found it.
