From the Discovering Millard County magazine:
"Heading from Fillmore to Delta: go west from Fillmore on State
Road 100 to Fowell, continue west until the road ends. Turn north,
drive appox. one mile on a paved road until the road ends. After
turning left, the pavement ends about 100 yards further, turning
into an improved gravel road. Follow the road northwesterly around
the lava flow. The ditch paralleling the left side of the road
often provides plenty of wildlife to watch, such as eagles, hawks
and pheasants. About 2 miles north of Fowell there is an
interesting ice cave a short hike from the road. Look for a small
bridge crossing the irrigation ditch on the west side of the
road."
THIS IS THE CACHE LOCATION AND THE PLACE TO PARK. Now duely
noted by a cache, so you can find the ice caves. A little less work
for the next persons trying to find the ice caves.
"Follow a faint trail north, then west through tall sage brush
to the inset of the lava-flow. Walk up a ramp-like lava cinder path
and down into a sunken grotto on the other side. (Perhaps a tenth
of a mile.) There are two old wood box-like structures at the
bottom that act as entries to the cave/crevices. When you step down
into the 3-ft-deep hole, you will be amazed at how cool it becomes
immediately. Even though it may be 100+ degrees on the surface, you
may be kneeling on snow or ice even in July. Shine a flashlight
into the shallow cave an you will see icicles hanging down from the
cave's roof."
WARNING: Snakes like this area!!!
WARNING: Cave at your own risk!!!
