Plate 1458X. Cave Knoll 1872 – 2007 Viewed north across Lee Valley from Cave Knoll on the Lower Kolob Plateau in Zion National Park. Pole Canyon is in the distance. The cleared field in the retake is a private inholding. All woody species have increased. This includes pinyon, juniper, oak, mountain brush, ponderosa pine, and sagebrush. The vegetation today is entirely different from what it was in the past. This is due to an absence of low-intensity fires since European settlement.
