Fox Forest in Pictures

For this week’s Monday Geology Picture I shared a picture of a stone wall incorporating a large glacial erratic. I took this picture recently in Fox Forest in southern New Hampshire. Yesterday, my husband and I went on a lovely hike in the forest. We saw quite a few glacial erratics… parts of the forest are piled high with them! We also saw many stone walls incorporating glacially dropped stones. Most …


Monday Geology Picture: Glacial Erratics and a Stone Wall, Fox Forest, New Hampshire

This stone wall was built out of glacial erratics and incorporates a large glacial erratic that was most likely left in situ… that is, left more or less where the glacier deposited it. Today, the stone wall is located in the middle of a …

Monday Geology Picture: Glacial Erratic Boulder, New Hampshire

For this week’s Monday Geology Picture post I thought I’d share another shot of this stunning glacially deposited boulder. Enjoy!

This week, I thought I’d share a few more pictures of glacial erratics on Franklin Pierce Lake. Note the large sizes of these erratics and also how many of them are fairly angular. The erratics are mostly igneous and metamorphic rocks, …

Glacial Erratic: A rock which has been transported and deposited by a glacier and which has a different lithology than the rock upon which it has been deposited. Often, erratic rocks have an angular shape because they were broken off of bedrock by glaciers and have not yet had time to be weathered and rounded by water, wind, and other erosional forces. Glacial erratics can range in size from very …
