Abstract

In general, the work done during the summer of 1960 was a continuation of that done during 1959. Essentially no new projects were initiated, although some of the earlier work was expanded. General observations were made of visitor usage and of the activity of large mammals. More intensive and detailed studies were made of the vegetation, soil and atmospheric properties of selected "natural" sites and of the properties of trails and campsites under varying degrees of usage, including some enforced "non-usage" by the establishment of exclosures. Some additional plant collections were made. Project Number 90.
