I found the
National Weather Service Lightning Safety site today.
This may have been posted on an older thread, however I couldn't find it. Considering the weather this time of the year in the Sierra, it's a good resource regarding what to do if you are caught in storm with lightning.
Below are some tips from the web site:
Last Resort Outdoor Risk Reduction Tips
If you are caught outside with no safe shelter anywhere nearby the following actions may reduce your risk:
Immediately get off elevated areas such as hills, mountain ridges or peaks
Never lie flat on the ground
Never shelter under an isolated tree
Never use a cliff or rocky overhang for shelter
Immediately get out and away from ponds, lakes and other bodies of water
Stay away from objects that conduct electricity (barbed wire fences, power lines, windmills, etc.)
And another tip I found:
"If that's not possible to get inside, squat low to the ground on the balls of your feet, making yourself the smallest target possible and minimize contact with the ground. Then, as soon as possible, get out of the area."
