Columns
of the Giants
Located in Tuolomne County, California, near the
Dardanelle's on Hwy 108, the Column of the Giants were formed
from two or more lava flows. The cooling of the rock caused
shrinking that resulted in horizontal tensions that caused the
lava surface to crack into polygonal patterns. As the cooling
progressed deeper into the flow, so did the shrinkage; as a
consequence, the surface cracks extended deeper and deeper into
the lava as well producing the columns that can be seen today.
As the giant columns broke and fell, the resulting talus slope
covered up and helped preserve remnants of ancient ice fields.
Today this field is replenished each year by the winter snow
and cold temperatures. During the summer cold breezes can be
felt coming up through the talus material from the ice field
below creating a natural refrigerator among the rocks.
