Since 2016, Kristopher K. Townsend has been the webmaster and editor of this site, Discovering Lewis & Clark®. He has been actively photo-documenting the Lewis and Clark Trail since 1995. He attempts as closely as possible to re-create scenes as described in the journals including the same time of year, natural state, location, and weather. He has contributed numerous photos throughout the Discovering Lewis & Clark website.
Kris taught several years as a tenured instructor at Spokane Falls Community College. His courses included Internet programming and other information technology and computer science courses. During that time, he was also the series editor and an author of a popular college textbook series on Office Technology.
Shortly after the advent of the World Wide Web, he managed a web server featuring digital photos, digital video, and articles created by his Glenwood Heights Primary students. Topics included historical sites of Clark County (Washington State), wildflowers and birds of Clark County, and how-to videos for school’s physical education program.
