Since it was raining yesterday, I took a hike up to check out Harts Ledge. I agree with JBeta. The boulder field is one of the most impressive I have seen in NH. Some of them are as big as the biggest of Pawtuckaway and there was lots of high quality. I didn't even get down to see the lower cluster.
Access was really easy, 15 minutes along a nice, mellow logging road. Drive into Bartlett along rt 302. At the blinking light (Bear Notch Rd) take a right if coming from NConway, which takes you north through the village and across the Saco River. Immediately take a left onto Cobb Rd. In a couple miles it hooks away from the river and becomes Raccoon Run. Continue less than half a mile and it ends with a good dirt parking spot on the left. Hike in the logging road just right of the parking. Note: Handren's directions don't mention that the logging road immediately splits. Take the left, that traverses rather than the branch that heads directly up the hill. The logging road is nice and clear except for one short spot of thick goldenrod and later a downed tree. When the trail hooks down to the old shack the boulders are very obvious on the hillside above.
Handren lists the 20' crack towards the right side here as a V7 and 3 stars. It looked classic to mehttp://www.mountainproject.com/images/98/78/108319878_large_48a13c.jpg?1378219268
