It's awesome to see the Park Rangers on top of the situation so quickly. Preparedness is #1. I've been group group leader several times down into the Grand Canyon NP and tell my folks to be over prepared for the worst. Carry a first aid kit and snake bite kit which includes both a sling for injured bones and a burn kit for accidents just as this. Hopefully more Fed $$$ will become available to assist in the proper sustaining of these precious resources for both the environment as well as the public who wish to view them. Can't wait to get to Yellowstone, will be there for a week in June.
