As part of our 2025 History Talks, Heidi Sproat will present a program on the Truckee-Donner Historical Society's online Image Collection at Truckee Tahoe Airport on August 19, 2025. The talk will cover what kinds of images are available for public viewing from the Truckee-Donner Historical Society's Image Collection, and what photos call tell us about the times, and how best to "date" undated photos. Heidi has uploaded over 3,200 images into this online collection which is fully searchable by collection, subject matter, and descriptive items in the photos. She and other members of the Historical Society have done extensive research, written numerous articles, and made presentations about Truckee's Winter Carnivals, Truckee in the 1940s - Shortages, Scrap Metal and Sacrifice, and Truckee Mythbusters. Articles include topics ranging from the Donner Cross, the 1960 Donner Ridge Fire, McGlashan's Butterfly Collection, local airplane fatalities, and much more. These articles are posted on the truckeehistory.org website.
