Pediment Arch Part 2



These long red sandstone sticks are a naturally formed geological phenomena. It is quarried in only a few places in  New Mexico . Here Kyle is showing a class of local Gualala students how we can these split these huge stones long ways with feather and wedges to make even thinner sticks.



Kyle and Sean have painstakingly shaped and fitted together both pairs of supporting stick posts for the pediment arch and lowered them into the ground using a simple tripod and a complicated machine called a Gradal. Concrete was used to hold the posts permanently in place.
