GRAHAMSVILLE, NY — Author Robi Josephson will give a talk at the Time and the Valleys Museum on Sunday, October 25 at 2 p.m. The topic is her new book with co-author Bob Larsen, “An Unforgiving Land: Hardscrabble Life in the Traps, a Vanished Shawangunk Mountain Hamlet.” Refreshments and museum admission are included, and signed books will be available for sale.

The protected Shawangunk Mountain Range in Ulster County is “one of Earth’s last great places,” a hikers’ and rock climbers’ paradise, but it was not always this way. According to Josephson’s book, from early post-Revolutionary days through World War II, a few hardy families scratched out a living atop the mountain, defying an unforgiving and isolated terrain. For generations they lived off the land, working subsistence farms and harvesting raw materials from the forest and earth.

The museum is open through October on weekends from 12 noon to 4 p.m. The suggested donation for admission is $5 for adults, $2 for children age six to 16. Visit www.timeandthevalleysmuseum.org
