We headed up for a casual day to thunder shower cave and GMZ to check out some of the other tony grove caves in the area which was a nice get away from all of the people in the surrounding campgrounds and cities due to the holiday weekend.

 After parking on the side of the road in the full capacity parking lot of Tony Grove, we headed up the mountain to find Thunder Shower cave.

 The entrance to Thundershower reminds me a bit of Valhalla with the inverted canyon undercut and the hole yet a bit smaller and not a 224ft drop that Valhalla has, this drop might have been 60ft total.

 There was a sloping snow cone at the bottom of the cave which took us down to the passage leading to the large room at the bottom.  Once we were both down, we worked our way over to the lightly sloping ledge and continued to go down to this 50 x 30 ft. room.

 There were a few formations on the walls but there was not too much to see down here IMO.

 I understand that the passage continues and goes into a loop back to where you start and that is the cave but I have also read about some side leads being pursued to see if the cave might turn into another main drain cave.

 The cave is indeed interested especially at the entrance but I wouldn't say this is a destination cave unless you want to add a few caves to the day and visit the beautiful north Utah area.

 Thunder shower cave got its name for a group that took shelter in the cave when a thunder storm came into their area and the group hid inside the cave to avoid the storm.  I can see how there would be some good spots to hide in there.

I have not found a map for thunder shower cave yet which tells me that a survey of the cave will be some good practice and a nice addition to the cartography section.

 This cave is absolutely worth a visit and good place to hangout in the Alpine terrain 8200ft up.  We de rigged everything and headed over to GMZ cave next.
