The last known photograph of Eric Robinson, captured by another hiker at Fox Lake on July 30, 2011. The second image shows a basic map of the High Uintas Wilderness. Eric was hiking the Uinta Highline Trail, highlighted in yellow. The sighting occurred at the far right side of the map. Eric’s planned exit was at the far left side. This meant the search area spanned the entire expanse of wilderness between those two points. Hear the story of the search for Eric in the Uinta Triangle podcast.
