Elizabeth L. Horn began her love affair with Crater Lake
National Park while a seasonal naturalist and did graduate work there leading to
a MS from Purdue University (1966). She has published several popular wildflower
guides covering the Oregon coast and the Cascade and Sierra Nevada mountains.
She retired from the US Forest Service and lives in West Yellowstone, Montana,
but returns to Crater Lake often to monitor her plots in the Pumice Desert.
