Jason Houston and Hal Clifford have delivered short gems of films to Mountainfilm for the past several years — vignettes that offer slice-of-life glimpses into unusual characters. This year, the character is not so unusual: She is a quite normal, if beguiling, little girl. In fact, she’s Houston’s daughter, and she’s something of an authority on climbing, especially as it relates to climbing walls and, even more specifically, a wall in her garage that she helps to build. Her goal in climbing? To get to the top.
