Find safe shelter among dense, small trees in lower areas, in a boulder field, or a cave. If this is not possible, lie down flat on the ground. In all cases, remove metal frame backpacks and metal tent poles. Equipment for summer weather can include tents, ponchos, rain slicker, rain hat, and extra clothing. As stated, plan for the worst weather, carry the Ten Essentials, and you should be okay.
Many unexpected things can happen during a wilderness trip.
These include injury, getting lost, illness, or the possibility of a forest fire. It is essential that you have adequate first aid knowledge to help yourself. Treat the injury if you can and make the victim comfortable. If rescue is delayed, make an emergency shelter. Do not move until help arrives unless there is more danger in remaining where you are.
