Description
Alkali Flat starts at the very back end of Dunes Drive, near the northwest corner of the loop. Look for a trailhead sign near a parking area on the west side of the road.As mentioned above, Alkali Flat isn't a trail in the traditional sense. Instead, hikers will be following a series of orange markers across the dunes. Spaced no more than six to eight hundred feet apart, they stand out well from the white sand and are generally easy to locate. With that said, if the next marker isn't visible, turn around. Once the trail moves past the first couple dunes, there will be very few visual reference points other than the mountains, and nothing to indicate the direction of the parking lot. There are also a few shorter, white and orange markers, and some posts showing mileage and the turnaround point. These are almost always co-located with the larger orange markers.One helpful aid is the tracks of visitors (and ranger vehicles) who have taken the trail previously. Tracks are usually well-formed, and last well, except in the windiest seasons. Look for tire treads to show the easiest way to take on steep sections. The first few hundred feet of Alkali Flat are through a flat basin between dunes. After passing another trailhead/warning sign, the markers split off to the west and northwest. Clockwise is the recommended direction, so head left. For the next two miles, the trail follows the markers up and down dunes. Winds are generally out of the west, meaning the steeper side of the dunes face east. It's a steep hike up in many cases, so look for easier routes around the sides. Slant climbs can help as well.A water tower and some large buildings are visible to the northwest around the mile and a half point. This is the National Radar Cross Section Test Facility, part of the White Sands Missile Range. Barely visible in the distance beyond are the hangars and buildings of White Sands Space Harbor, one of the alternate landing sites for the space shuttle program.Eventually the dunes flatten out to the trail's namesake alkali flats. These flatlands stretch all the way to the base of the San Andreas mountain range, about ten miles away. While a nice relief from the constant climbing and descending, the flat section doesn't last long; the trail reaches its apex near the two and a half mile point and heads back to the east. The route back is about the same, with the advantage of the steep sections now being in the form of descents. Nice views of Sierra Blanca can be had towards the northeast. Eventually, the trail converges back at the starting basin.
History & Background
Wedged between the rugged mountains and arid desert of southern NM, White Sands has a storied history. After several failed attempts to protect the unique area as a game preserve or national park, Tom Charles, a civic booster from nearby Alamogordo, was able to gain support to convince President Hoover to declare it as a Nat'l Monument in 1933. Charles would go on to be the first custodian of the monument, and after his retirement, its first commercial vendor. It became a Nat'l Park in 2019 and continues to be a popular year-round attraction for hiking, camping, and sledding.Surrounded by the White Sands Missile Range, Holloman Air Force Base, and Fort Bliss, the area has long been home to military activity, including the nearby Trinity Site. Space development is also a part of local history. The trail is only a few miles from White Sands Space Harbor, part of the shuttle program, and just over the mountains lies Spaceport America, the world's first commercial spaceport.
