Strenuous hike yields fine vistas

Fortification Hill, just east of Hoover Dam on the Arizona side of Lake Mead National Recreation Area, towers about 2,000 feet above Lake Mead’s Boulder Basin. Although it looks impenetrable, there is a short but strenuous route to the top where you will be treated to some of the finest views in the park.

The “hill” is actually a mesa that was formed 5 million years ago through a series of volcanic episodes. The trail will be 3 to 4 miles round-trip and has an elevation gain of 1,360 feet. It is not a hike for children or anyone that can’t do some short but difficult rock scrambling or handle a steep scree slope.

The trailhead is at an elevation of 2,326 feet. From here, walk up the wash and go right up the path that brings you up on the ridge. The trail undulates for about a mile and then you will reach a well-defined saddle. Here is a large pile of 3- to 4-foot basalt boulders that seem totally out of place.

From here you head up the steep scree slope toward the base of the cliffs. This isn’t too hard to hike on the way up, but on the return you will definitely want a hiking pole for stability. I have seen several people fall.

Once at the base of the cliffs you will go right, carefully working your way for about 50 yards. Keep a sharp eye out on your left for the break in the cliff walls, which will be your travel route up. There has been a cairn there in the past but I never rely on cairns as they often get knocked down. If the trail starts to descend for more than 20 feet, turn around as you have gone too far. There are extreme drop-offs in this area.

The initial climb up the cleft is the hardest and after that just follow the easiest route up to the top of the mesa. Follow the obvious trail, which heads first to the southwest and then west to the rock outcropping. On top you will find creosote and barrel cactus as well as Mojave yucca and silver cholla.

From the rocky outcropping the views are fabulous. To the northwest you can see the Strip and beyond to the Spring Mountains including its tallest peak, Mount Charleston. To the north lies the Muddy Mountains. Below you at the base of Fortification are the colorful Paint Pots. The reds, pinks and oranges are the result of geothermal activity.

While there, find the hiker’s register and enter what information you want to share and be sure to glance at other hikers’ notes. Some of them are a fun read.

This hike is fully exposed to the sun the entire way. Be sure to wear a hat, sunscreen and bring plenty of water. The one big caveat with this hike is the constant helicopter traffic overhead on scenic flights to the Grand Canyon. They are loud and after the first dozen or so it becomes very irritating.

To drive to the trailhead you will need a four-wheel drive, high-clearance vehicle with good off-road tires for the last 2½ miles of driving. Do not drive the road if it is raining or there is a threat of rain as flash flooding occurs here.

Go left and under the highway and continue on the gravel road for about 5.2 miles. Turn right on Approved Road 70C and drive about 2.5 miles to parking and trailhead located on your left.
