Lowell Observatory Thinning Project

A forest restoration effort, that includes thinning small- to medium-sized ponderosa pine trees, has officially begun on Observatory Mesa – on the Lowell Observatory owned Section 17. The main objective of the project is to restore the forest and reduce wildfire risk for both the historic and valued Lowell Observatory and the greater Flagstaff community. Given Lowell Observatory lies on the northwest side of the City of Flagstaff and is only one mile from City Hall and downtown, forest restoration work will contribute to creating resilient forests in the face of increasing wildfire risk. GFFP is leading the project in conjunction with many partners like Coconino County, the City of Flagstaff, Campbell Global, and SRP. Please check this webpage for frequent updates, and see below for more information.

See the full press release.

Trail Closure maps/updates:

As forest thinning operations move through Section 17 on the Lowell Observatory property, see this section for trail closure maps. These maps will be updated as the logger moves through the property.
