What’s open, what isn’t: latest on on local trails, roads, campgrounds
The drought winter has allowed more access to Mammoth-area trails, roads and campgrounds than is normal for late May and June, but many high country trails are still covered in snow if they are above 10,000 elevation and/or if they are on north-facing, shaded slopes.
Several campgrounds are also still closed, due to issues with infrastructure or access.
According to the Inyo National Forest, the following is a list of the status of most of the area roads, campgrounds and trails, with a new update expected on Friday, May 30. That update will be posted at mammothtimes..com.
