There are a few links below that provide information about the Outing Club destination. The first link shows a large map of the White Mountain National Forest. Look on the Maine/New Hampshire border for Wild River Campground. Explore a little to find out about the area.

This LINK will let you search for topographic maps of many United States locations. Search Hastings, ME. You will get on screen a topographic map that shows the Wild River Road when it turns southwest off of Route 113 (Evans Notch Road) Topozone will allow you to then move around that area. The campground is not noted, but continue moving around in search of Moriah Brook and Moriah Gorge.
