Overview

From Las Vegas, this is a long drive and a short walk to a big hole in the ground. The mountains are limestone, and over the millennia, moving water dissolved out a long tubular cave that is about 900 ft long, 70-90 ft wide, and 60-70 ft high. At the west end of the cave, near the surface, the roof collapsed and created a sinkhole that serves as the entrance. Getting into the cave requires an 80 ft rappel, the last 15 feet of which is overhanging. Getting back out, obviously, requires technical rope-climbing techniques. Towards the middle of the cave, a squeeze through a hole and a short downclimb are easier and safer with a short rope.

There is considerable breakdown rubble (huge boulders) to climb around, but much of it supports stalagmites, flowstone, and popcorn formations. The walls of the cave and the side chambers support many delicate formations, including some that have grown against gravity. The back of the cave contains a huge column, a number of water-filled pools, lots of beautiful flowstone, and amazing crystals growing out of the walls. Dirt and animal bones at the end of the cave suggest that the end isn't really the end.

Watch Out

Other than the standard warnings about hiking in the desert, especially the section about holes in the ground, ...this is a technical cave that requires an overhanging rappel. Getting into the cave provides a variety of places to fall and get hurt, as vertical rockcraft always is dangerous, and cave rescues are complicated, difficult, and painful. The floor is slippery in wet portions of the cave. Watch for hard things hang down from the ceiling.

This route requires ropes. If you don't know how to use ropes, go with someone who does, get some training, or visit a walk-in cave. This cave isn't interesting enough to risk getting hurt, let alone the slow and painful rescue.

While hiking, please respect the land and the other people out there, and try to Leave No Trace of your passage. Rescue would be time consuming and difficult in this cave, so bring the 10 Essentials, a hard hat, and 3 sources of light per person. Make sure this route is of the appropriate difficulty for your skills. This cave is in the Far South Eagens Wilderness Area, so pay particular attention to respecting the land.

Caves are delicate places: don't touch cave formations because the oils on your hand will hinder or change the growth patterns. Don't break any formations; don't bring back any souvenirs from the cave.

Trail Guide
Getting to the Trailhead

Whipple Cave is located on the west side of the Far South Egan Range, northeast of Sunnyside (way north of Alamo and Hiko), about 200 miles north of Las Vegas.

From Las Vegas, drive north on Interstate-15 for 21 miles to Highway 93 (Exit 64) (Site 674). Exit the interstate, turn left onto Highway 93, and drive north for 72 miles to Alamo (Site 675). The Del Pueblo (Exxon Station) is the last place for good food (try the green chili), and the little motel about 1/4 mile south of the Del Pueblo is acceptable if you are tired and don’t want to sleep out. Continue north on Highway 93 for another 9 miles to Ash Spring (Site 444). This is the last gasoline before the cave.

From Ash Spring, drive north on Highway 93 for 2 miles to Highway 318 (Site 677). Turn left onto Highway 318 and drive west for about 0.7 miles to the Y-intersection with Highway 375 (Site 676). Stay to the right on the curve and follow Highway 318 north towards Hiko.

Pass Hiko and continue north for about 65 miles to Sunnyside and the Kirtch Wildlife Management Area. Continue north for a couple of miles to the unmarked Whipple Cave turnoff (Site 01). The turnoff to the cave is marked by a barbwire gate about a half-mile north of Mile Marker 23. The gate is marked #48. Go through the gate and drive northeast, staying to the right at all forks. Eventually the road curves gradually to the right (southeast) and runs up into a canyon. In the canyon, a short, high-clearance-vehicle side road to the left runs back northwest to a saddle and campsite near the cave entrance (Site 02). Without a high-clearance vehicle, park at the turnoff and walk the last 2-3 minutes to the end of the road.

The Hike

The trailhead (Table 2, Waypoint 02) is located on a hillside at the bottom edge of the Pinyon-Juniper Woodland (Upper Sonoran Life Zone) with grand view out over the sagebrush flats to the west. The trees are Singleleaf Pinyon and One-seed Juniper. Shrub species include cliff rose, apache plume, banana yucca, Mormon tea, grasses, and a few other shrubs.

From the trailhead, a use-trail runs north into the Far South Eagens Wilderness Area. The cave entrance (Wpt. 03) is about 120 yards up the trail.

The Cave

There is a 2-bolt anchor set above a ledge at the edge of the abyss. Using short ropes or long pieces of webbing, trees and large shrubs can be used as backup anchors. A 165-ft rope, doubled over and tied separately to the two bolts, is just long enough to reach the bottom. Other than a few carabineers and some webbing, no other hardware is needed for the anchor.

Enter the cave by rappelling about 70-ft, the last 15 feet of which are overhanging. The bottom of the rappel is a flattish area, about 60 ft wide, at the top of a large, dirty scree slope that trails off into the darkness. Sign-in at the register located near the bottom of the rappel.

Note: Cave dimensions are based on a map produced by Steven Ross in 1993, which is available on the Southern Nevada Grotto Website.

Start into the darkness by hiking (sliding) down the steep scree slope. At the bottom of the scree slope, about 200 ft in, a side tube runs northeast (left). The formations inside this tube are some of the most remarkable in the cave. The main cave at this point is about 75 ft wide and the ceiling is about 60 ft high.

The most direct line through the cave runs along the north (left) wall, but don’t miss the formations and flowstone among the breakdown rubble and along the south (right) wall. Staying along the north wall until about 475 ft out, the cave pinches down to a narrow crawl hole between the wall and huge breakdown boulders (this is a hole, not a tube). Immediately before the crawl hole, the cave is about 90 ft wide and the ceiling is about 55 ft high.

Getting into the back section of the cave requires squeezing backwards (feet first) through the narrow crawl hole and dropping onto a flat-topped boulder without falling into the 18-inch-wide slot directly below the crawl hole (space between breakdown boulders). This is a bit of a stretch and a good place for a short (10-12 ft) rope. Use webbing to tie off the chockstone boulder above the crawl hole, and use the rope to rappel (or just as a handline) to safeguard getting onto the flat-topped boulder. There are no good footholds.

Squeezing through the hole puts you atop a flat-topped boulder in the back half of the cave. At this point, the cave is about 70 ft wide and the ceiling is about 55 ft high. The end of the cave is another 420 ft back.

From the top of the flat-topped boulder, slide off the overhanging south (right) side onto a sloping wall, but don’t fall into the small, deep hole at the bottom of the sloping wall. This is another good spot for a short rappel or a hand-line, especially when the sloping wall is dripping wet. When I go back, I’ll just rappel through the hole and off the southeast (far right) side of the flat-topped boulder using my 60-ft rope (30 ft probably would be sufficient).

After getting off the flat-topped boulder, scramble among the breakdown rubble to the massive column, a huge structure standing in the center of the cavern. The column is huge, looking taller than the reported 30 ft. Based on the cave map, the column should be about 70-ft tall. Beyond the column are rimstone pools, amazing flowstone on the walls, crystals growing out and up from the wall, lots of popcorn, and other amazing cave formations. At the far end of the cave, dirt and animal bones provide ample material for speculation.
