Elzada Clover and Lois Jotter Cutter were the first women to successfully run the length of the river in the Grand Canyon. Dr. Elzada Clover was a botanist working as the curator of the University of Michigan’s botanical gardens. She was originally planning a mule trip through the Grand Canyon to identify cacti and succulents but conspired with Norm Nevills to turn it into a river trip. Lois Jotter Cutter was a graduate student at the time and joined her on the trip. Clover became the first botanist to record plant life in the canyon. A graduate student on the trip left after a conflict and was replaced with Emery Kolb.
