Merriam Crater ("Dixon White Memorial Flight Park") is a northern Arizona site and has launches that provide great flying for new P2 pilots to experienced thermal/XC pilots and has a long history of pilots from all over the world flying here. It is mandatory to get with local pilots prior to arriving due to the unique, highly challenging weather to forecast and extreme high desert conditions here! It has been an official flight park since 1991 and serves as a memorial to the late paragliding instructor, Dixon White. Merriam Crater is not a USHPA/RRRG insured site, and sits on the edge of the Navajo Indian reservation and the Little Colorado River Valley (LCR). This dormant volcanic cinder cone provides treeless, 180-degree launch possibilities that range from the morning and evening sled ride to long XC's as well as glass off conditions at times for both hang glider and paraglider pilots.


  1. All pilots must be current members of the Arizona Hang Gliding and Paragliding Association (AZHPA). Membership info here.

  2. All pilots must be current members of the United States Hang Gliding and Paragliding Association (USHPA) and have ratings listed below.

  3. All pilots must have a current H2/P2 or higher USHPA rating while launching and flying. All P2 pilots flying after 9:30 AM and before 5:30 PM year round must be accompanied by a local P3 pilot familiar with the site.

  4. For all pilots, on-site briefings from a local, qualified pilot are a requirement. This sponsor shall be a qualified pilot that has experience flying that individual site.

  5. Visiting pilots can obtain a visiting pilot pass here and show the registration confirmation as proof.

  6. "TUR" (turbulence) special skill endorsement is required.

  7. Mini wings and speed wings may be flown here in certain conditions with an USHPA M1 or M2 Rating and pilots must contact prior to get detailed site and conditions briefing from local M2 rated pilots.

General Rules That Must Be Adhered To By All Pilots

  1. Do not launch anywhere except for the designated launching areas. (See Images Below)

  2. Do not land anywhere except for in the designated landing areas. (See Images Below)

  3. There are nearby one-square-mile parcels of land which are privately owned and not part of the Merriam Flight Park (see image below). Please do not stray off of the main Merriam access road.

  4. Drive slow, keep dust to a minimum.

  5. Do not land in the old hang glider LZ on the east side of Merriam.

  6. 4x4 vehicles only on all roads that lead to launch. High clearance vehicles are preferred.

  7. Do not park vehicles directly behind/downwind of launching pilots.

  8. All vehicles carrying pilots should have a shovel on board. Please repair your own spin outs and ruts.

  9. Stay on the roads at all costs. The soft cinders can cut a ditch and erode quite quickly. Vegetation has a hard time coming back once trampled. If you are a visitor and have any questions about access road use or current conditions, ask a local pilot. Don't just "go for it."

  10. Let's all work together to maintain a good relationship with land owners and keep Merriam easily accessible.

Know Before You Go

Be aware of land ownership in the area. Directly south of Merriam Crater is a private cinder mining operation. Three miles to the east is the border of the Navajo Nation. All areas on the Navajo Nation are closed to non-Navajos unless you have a valid camping, hiking, or backcountry permit issued by Navajo Parks and Recreation Department or other duly delegated tribal authority. Failure to have a permit is considered Trespassing on a Federal Indian Reservation. That doesn't mean you cannot visit certain areas. As well, there are other privately held parcels just to the north of Merriam, including the lower bench and the "T" LZ. Respect private property and land in designated areas. See below. A GroupMe chat room called "PG Flagstaff" serves this flying site.

Gust differential can and will change rapidly. Thorough weather forecasting mixed with local weather and site knowledge is mandatory. Always study conditions 30 minutes minimum before setting up to launch. Arrive early to watch conditions develop.

Driving Directions: From Flagstaff, head east on I-40 to the Winona exit 211. Go left at the top of the ramp and continue to the northwest on that highway. After a couple miles you'll come to your first paved road on your right called Leupp Rd. Turn here and head NE. After about 1/2 mile you'll see a restaurant-bar called the 2 Bar 3. This is a common meeting point for pilots before heading out to the hill and a great place to wait out the often violent midday conditions.

From the 2 Bar 3 you continue out Leupp Rd. towards the Navajo reservation. Pay attention to the speed limit, 35 at first then 45 as you pass through a small commercial zone. Once past this point the speed limit is 50 m.p.h. The miles will pass by and you'll soon be looking at two cinder cones: Merriam will be on your left. At mile marker 440 you should start paying attention.

Just before you pass the mountain entirely, and before you get to the mailboxes on right, turn left at the break in the fence with a cattle guard (see image). Continue to the north driving towards the hill and crossing over all other roads and passing over a rocky section. You will cross a second cattle guard and continue on the same road. 

Roughly 1/4 mile later you'll see another bald area on your right. On your left is a two-track road that heads toward the hill. STAY OFF OF THIS ROAD! The land owner does not want us there. Continue to the north until you see a fence and another cattle guard. You'll go left before crossing and follow the fence line (on right of road) up the hill to the west.

By the time you reach the top of the fence line you should clearly see the road up to the top. At the base of the steep part of the road is the “Y” (or “East”) LZ. If you are going to continue up the hill please put your vehicle in 4 Low if it isn't already. If you would like to go to the Lower (“North”) Bench you can turn around and veer left and cruise around to the north. You'll see a concrete monument with a windsock: this is the North Bench.

Set-up Area HG: Generous flat area behind launch. Do not park directly downwind of vehicles

Set-up Area PG: Generous flat area behind launch. Do not park directly downwind of vehicles


Flying and Local Weather Wisdom

The simplicity of the round hill makes for some great options in the right conditions. Yet it is easy to overlook some more complex scenarios that may exist. First and foremost is the LCR inversion.

The top of Merriam Crater is the same approximate elevation as the 2 Bar 3 restaurant-bar you passed on your way to the hill: 6,400 ft. The top of Merriam is 6,800 ft., close to the average elevation of Flagstaff. If you continued out Leupp Rd. you would come to the town of Leupp which is an historic crossing point of the Little Colorado River (LCR) which lies at 4,700 ft. From this point the road begins to climb up to the mesas and mountains of the Hopi and Navajo reservations making for a 2,300 ft. deep valley that gets deeper as it nears the Grand Canyon.

Most nights this valley is filled with cool air and a thick inversion forms. The inversion usually builds up beyond the top of Merriam each night. To better understand what is going on, the locals look at the Winslow and surrounding Skew-T charts to get an idea of what is happening in the LCR. We also look at the winds aloft in Flagstaff and for around a 50-100 mile area but sometimes the Winslow data usually shows us the inversion a little more clearly.

If it is a standard high pressure day with light winds aloft you'll find that the day will sometimes start out light and variable and as the day progresses become more northerly, even if there are light winds aloft from another direction. If there are strong winds aloft and you get to the hill to find light winds on the surface, plan on calling it quits early before the inversion breaks. When you start to see a light base flow become still and conditions become variable/switchy, the locals have learned this is a warning and you should go home to fly another day.

Ground clearance mid-day: For the aspiring P3 or the hungry P4, this has seemed to cause more incidents at Merriam than any other issue. When thermal flying mid-day, remember you are not ridge soaring and the closer to the hill you are, the smaller, sharper and less organized the thermals are as you are flying into the base of them. The best pilots at Merriam watch the cycles carefully, launch at the end of a lull and fly into the top of the thermals that have traveled up the valley and thus are farther away from the mountain and launch area. They often always pass up thermals near launch to get out away from the hill and into a more usable piece of lift. You don’t want to be the pilot that was scratching near the hill and left their own crater in Merriam Crater.

Some wonderful glass-offs can kick off as the shadows get long in the late afternoon. Time it just right and you can be floating in soft, buoyant air well above launch until sunset. Conditions just before and after sunset can quickly change, go catabatic and go variable at times.

Finally, keep in mind that Merriam Crater is somewhat featureless and round, so it's easy to forget what "side" of the hill you are on. Always be cognizant of wind direction to avoid getting pulled into side-hill venturi and sink. The cinders are a little softer than dirt, but not much.

Keep site briefing and situational awareness in mind at all times and give extra safety margin due to high desert conditions. Conditions can change rapidly, especially during the summer monsoon season when either nearby overdevelopment, virga, or gust fronts from distant thunderstorms, can kick up nasty unpredictable and non-paragliding type flying weather quickly. Please be an active pilot. Keep final glide/approach to landing zone over land-able terrain. Clear the LZ immediately. Dust devils are not just a phenomenon of the lower desert. The high country gets them, too. Kiting is not allowed in the entire area, especially launch, past 9 AM and before 6 pm for obvious reasons.


Hot days in the summer and below-freezing weather in winter are extremely unforgiving on unprepared pilots, outdated equipment and pilots not giving extra margin of safety within their operating limitations. Adequate preparation, a sufficient understanding of local weather forecasting and a local on-site briefing is required. Dehydration is a real possibility even during winter months. Give yourself an extra margin for error due to the terrain and weather conditions. 

All pilots must read the General Site Guidelines prior to arrival.

Restrictions: No airspace restrictions in the immediate area. Know where the Navajo Nation begins to the east of launch. Please refer to the “Know Before You Go” section on this page, above.

HG and PG Designated Landing Zones

Landing zone information has been covered above. Do not overfly cars and spectators. Do not scratch, especially during thermic parts of the day.

Note: Pilots must familiarize themselves with this information before arriving, and this information does not replace the need for an in-person site briefing from a qualified, local pilot or instructor familiar with the area and experienced in flying the site.
