Yosemite National Park Announces Release of the Parkwide Communication Data Network Environmental Assessment
Yosemite National Park announces the release of the Communication Data Network (CDN) Environmental Assessment (EA) for public review. The purpose of the proposed project is to upgrade Yosemite’s internal communications system with more reliable, modern technology and create an efficient communications backbone to support all the park communication needs. Public scoping began in November 2008, followed by public site visits in spring 2009. Comments and concerns received from the public, tribes, and other agencies have contributed to the development and refinement of a range of alternatives presented in this EA. The EA describes the “no action” and two action alternatives, presents analysis of the potential environmental impacts of each, and includes mitigation measures to avoid or minimize impacts to sensitive resources.

Rockfall events have helped shape many of the outstanding features along Yosemite Valley's walls, including Royal Arches, North Dome, and Half Dome. Giant talus slopes that slant away from the Valley walls accumulate debris with each rockfall event.
