If you visit South Valley, Deer Creek Canyon or Hildebrand park on any given morning, you just might see Jean Viste hiking along a trail.
For nearly 17 years the Ken Caryl resident has been walking trails in South Valley, Deer Creek Canyon and other area parks while serving as a volunteer for Jeffco Open Space. She has helped hikers locate their cars, closed trails where the presence of bears and mountain lions presented danger, and administered first-aid to the injured.
