From the northBoulder Hill from the north

Boulder Hill is a surprisingly scrappy and rugged little peak in the eastern Black Hills near Rapid City, South Dakota. The peak is a splendid example of the surprising beauty of the Black Hills. The 10 or so minutes of scrambling at the top of the hill came to me as a very pleasant surprise. The summit area is characterized by two highpoints: A lower, southern highpoint with the ruins of an old lookout on top from which broad views can be enjoyed, and a smaller, northern true highpoint which includes the USGS marker.

The views from the top of this peak are mostly open and quite nice! Rolling hills are all around. Parts of Rapid City can be seen in the distance to the northeast and Harney Peak dominates the horizon to the southwest. The easiest route to the summit is a Class 2+ jaunt through and over boulders and up ramps, and this is a good introduction to scrambling for beginners or kids.
