Oscar W. Tollefson, who had almost graduated from the Univ. of Colorado (Ph D in geology), found himself sitting next to Colorado State College (CSC) President Bill Ross on a commercial flight between Washington, D.C. and Denver. Tolley, as he was universally known in professional circles, was the loquacious sort and so of course he struck up a conversation with a guy who, it turns out, was an amateur rock , fossil, and mineral collector. Bill Ross came from a background in buildings and grounds and knew a lot about earth materials and weather! Though we don’t know exactly what was said in that four hours, we do know that Bill Ross recognized a rare enthusiasm for teaching and learning in the young Tolley. Ross also probably recognized that Tolley’s persuasiveness and persistence would go a long way at the growing College. The Earth Sciences academic program was founded at Colorado State College (CSC) in 1956 by Dr.

  • ZOOLOGY Exploring the Biodiversity of Colorado and Theworld
    CHAPTER 4 — ZOOLOGY Exploring the Biodiversity of Colorado and the World CHAPTER 4 ZOOLOGY Exploring the Biodiversity of Colorado and the World Jeffrey T. Stephenson, Before the Museum Paula E. Cushing, The first collections of specimens that make up what is now the Denver John R. Demboski, and Museum of Nature & Science were actually established well before the Frank-T. Krell founding of the institution in 1900, the selection of a board of trustees, or the construction of a building to house and exhibit the specimens. Edwin Carter (1830–1900) (Fig. 4.1) collected Colorado birds and mammals from the 1860s through the 1890s. Born in New York in 1830, Carter arrived in Colorado in 1859 hoping to make it rich in the goldfields, but he soon became interested in the region’s natural history. He learned hide tanning and, as his prospects for hitting the mother lode faded, he earned his living selling buckskin clothing that he handcrafted. Carter supplemented these earnings by mar- keting foodstuffs and other provisions to the growing population of successful and (mostly) unsuccessful prospectors flooding the region. His interest in nature turned to concern as he observed dwindling numbers of mammals and birds, owing largely to habitat destruction and overhunting. Period photographs of the area’s mining district show a landscape largely denuded of vegetation. By the 1870s, Carter noted that many animal species were becoming scarce. The state’s forests were being devastated, ranches and farms were replacing open prairie, and some species, including the last native bison in Colorado, were on the verge of extirpation or extinction.

As a result, the course and timing of freshwater diatom evolution and paleogeography are virtually uncharted. The rare pre-Neogene diatoms on record show a low diversity (taxonomic richness).
