Experience Idaho by helping professional archaeologists and historians preserve its history on public lands! Passport in Time (PIT) is a national volunteer program of the U.S. Forest Service and the Bureau of Land Management. PIT volunteers work with professional archaeologists and historians on activities ranging from survey to excavation to laboratory analysis and curation of artifacts. In Idaho, PIT projects involve such diverse activities as locating and photographing tree carvings left by Basque sheepherders, restoring a historic fire lookout tower, locating sections of the Lewis & Clark Trail, or recording ancient rock art in a remote wilderness. Volunteering with PIT is a wonderful way to see Idaho’s national forests and grasslands and to get an in-depth look at history. As a PIT volunteer, you will participate in important historical research and help land managers preserve the places and memories important to our nation’s history for our children and grandchildren.
