We need not forget that this area was used for mining and still is. So you make come upon areas of old mining holes. So heed the fenced off area! Plus it gets cold or hot here so dress accordingly. Bring plenty of food and water with you, and please take your trash back with you. Respect the local fona too! Be sure you wear proper shoes since all of the area is dirt and rock, so trails are slippery. Also, the road does cross a railroad tracks, so beware. More importantly beware of how the roads can be affected if it rains here. It was very obvious by some of the condition of the dirt roads that they can be affected by flooding quite dangerously!
Sounds corny, but you wouldn't believe how many people that forget to drink enough liquid while in the desert. AQUA=LIFE
Keep it mind.
