General Park Overview:
 
"In old Hawai'i, if you had broken a law, the penalty was death.....Laws or kapu, governed every aspect of Hawaiian society. The penalty for breaking laws was certain death. Your only option for survival is to elude your pursuers and reach the nearest pu'uhonua, or place of refuge."

Earth Cache Lesson:
 
1. "Lava Trees are created when fast-flowing lava moves through a forest completely surrounding the moist trees. The lava cools on the outside as the tree is incinerated on the inside, leaving a lava shell in the shape of the tree. While some molds will reach several feet high, others will be merely stumps or even depressions. Sometimes lava trees will preserve the texture of the original bark. They are most often formed by smooth pahoehoe but occasionally a'a will create the same form." (www.hawaii-guide.com/big_island_of_hawaii/sights/tree_molds)
 
2.  Lava Tree Molds are created when fluid lava flows through dense tropical forest became chilled against the larger trees and tree ferns and later drained away. Trees growing in such an area are quickly covered with lava. The lava touching the tree causes the tree to burn out. ( >www.hawaii-guide.com/big_island_of_hawaii/sights/tree_molds)
 
At this location a lava tree mold was formed in lava as the wet trees chilled and cooled the lava as it surrounded them and thus were insulated from the intense heat of the surrounding flow. The cooling was rapid enough to preserve the shape though the tree burned away.
 
There are two types of lava on the Big Island. A'a is the most common. It cools down forming fragmented, rough, or blocky surfaces. Pahoehoe lava is smooth, billowy, or ropy surface. It has been likened to the appearance of a pan of chocolate brownies.
