From reading other online trip reports about the Hidden Bowl route, I don't think this is the way most others go, but it is where my journey took me. Before the headwall, there is a gully on the right side, and that gully (Class 4) is the easiest way up and out of this small bowl. From there, I continued to ascend up steep sandstone before eventually working left to gain the opening of Hidden Bowl proper.
