We've all seen the many stone walls in Dunbarton and tons of glacial rock scattered about in the woods, but you may not know that Dunbarton is home to a number of large glacial boulders, one of which is reportedly among the largest in southern New Hampshire.

Where did they come from? What are they made of? Join noted glacial geologist George Holt for a tour of some of the biggest in town and a glimpse into the secret life of the glacial boulder.

Meet at 10 a.m. Saturday, October 17 where the big powerlines cross NH Route 13 (Clinton Street) east of the Page's Corner/Jewett Rd intersection. Please park as far off the road as possible. The walk will total about 1 mile on uneven ground and take about 1 hour.

For more information contact hike leader George Holt at george@naturofm.com or 774-3294.
