Small sunrise and moonrise workshops in the white gypsum dunes of White Sands National Park, for six photographers at a time, with Paz Archuleta. Every hour on this page is one day, February 20, 2027: watch the line under the menu. That’s a pin, ten pixels tall, and its shadow at the length the sun would draw it in the dunes at that minute.

Three ways into the white

  1. Sunrise in the dunes

    Saturdays and Sundays, Nov 14 to Apr 25

    Meet an hour before sunrise at the visitor center, in the dunes before the gate opens, out by 9:30. About 3½ hours, a mile and a half of soft sand.

    Six photographers

    $165Book

  2. Moonrise on the full moon

    The six evenings below

    Meet 90 minutes before sunset. The long east shadows, the sunset, the earth’s shadow over the Sacramentos and the full moon coming up out of it. Out about two hours after moonrise.

    Six photographers

  3. Sun to moon

    Sat Feb 20, 2027 only

    The whole day the sun sets at 5:54 and the moon rises at 5:56: the sunrise, lunch and the edit at my table in Alamogordo, a nap, then the moonrise. One print of your best frame, mailed.

The morning, measured in shadows

Under each hour, a pin and its shadow at true length. The number is how many times longer the shadow is than the thing that casts it.

  1. 6:18 amsun −6° · no shadow yet

    Blue sand

    Civil dawn. The whole dunefield is one even blue-white and nothing casts a shadow. Behind us the full moon is going down into the San Andres. We set up on a crest I chose the afternoon before, facing west, because the mountains light first.

    The mountains first

    Sunrise comes over the Sacramentos behind us and lands on the San Andres, thirty miles west, before it reaches the sand. For about four minutes the range is rose and the dunes are still blue. Long lens, f/8, and don’t move.

    Every ripple

    The sun is two and a half degrees up and a ripple a quarter inch high throws a shadow five inches long. This is the twenty minutes the whole morning is for. Low, close, and expose for the white.

    One yucca

    The soaptree yucca on the slope east of the crest. Its stalk is about eight feet tall; at 7:15 its shadow is about eighty. We wait for it to reach the ripples and stop.

    Our own tracks

    Now the footprints are the subject, ours included. Every one holds a little pool of blue. We walk out along the line we made coming in.

    Flat white

    The shadows are down to twice the height of what makes them and the sand goes flat. We stop. Coffee at the cars at 9:30.

Paz Archuleta

“Noon is the one hour I’ll stand in front of a camera. Nothing out here has a shadow worth taking.”

I grew up in Tularosa, fifteen miles north of the dunes, and I didn’t photograph them until I was twenty-nine. My father drove a truck on the missile range for thirty-one years and kept an old film camera in the glovebox. One January Sunday in 2009 I borrowed it, went out at sunrise because he said that was when the sand turned blue, and shot one soaptree yucca and its shadow at 7:20 am. That print is still on my kitchen wall.

I spent twelve years printing for a portrait studio in Las Cruces, and every weekend I was in the dunes. I started taking people with me in 2014 and have run Gypsum under the park’s commercial use authorization since 2016. I keep it to six people because six tripods fit on one crest without anyone’s shadow in anyone’s frame.

Between the sunrise and the moonrise on Feb 20, you’ll eat lunch at my table in Alamogordo while we go through your morning on a big screen. Then go and sleep. The moon is at 5:56.

What to bring, and what you don’t need

Any camera, or your phone
Phones do well here. Set exposure to +1 or +1⅔: the white fools every meter into gray sand. We fix that in the first ten minutes.
A tripod for the moonrise
Not needed at sunrise. For the moon it is. I bring two to lend.
One lens, ideally
Gypsum is as fine as flour. Change lenses inside a bag, or bring a wide and a long on two bodies and don’t change at all.
Layers
February dawns are often below freezing; by 9 am it’s sixty. Gloves you can work buttons in.
Shoes you can empty
Soft sand, about a mile and a half, up and down dunes up to fifty or sixty feet. Some people go barefoot by 8:30; the gypsum stays cool.
Water and a headlamp
We walk in and out in the half-dark. Red light only once we’re on the crest.

Six photographers, one guide, all levels. Ages 12 and up with an adult.

From the crest

I booked it from Hamburg the week before I flew. Paz texted the meet time in Mountain Time and in mine, and at 6:43 exactly the mountains went pink.

Phone only. She showed me the exposure trick in the parking lot and my yucca is now my lock screen and my sister’s.
DoloresLas Cruces, Sunrise, Dec 2025
I shoot weddings for a living and I came for the moonrise. I’ve never seen anyone plan a crest around a two-minute gap. Worth the drive.

The evening, and the two minutes

  1. 4:30 pmsun 16° · shadow 3.5×

    Back in

    The moonrise group meets at 4:30 at the visitor center. Same crest, opposite direction: the shadows now run east, toward the Sacramentos and where the moon will come up.

  2. 5:30 pmsun 4.2° · shadow 13.6×

    The long east shadows

    Every ripple again, lit from the other side. I walk you down the crest one at a time so nobody’s shadow crosses anyone’s frame.

    Sunset

    The sun goes behind the San Andres a few minutes before the 5:54 on the almanac. Turn around: the pink band over the Sacramentos is the Belt of Venus, and the blue under it is the earth’s own shadow.

  4. 5:56 pmmoon on the horizon

    Moonrise

    Two minutes later the full moon comes up into the earth’s shadow, held back a few minutes by the Sacramentos. The sand is still pink, the moon is the same brightness as the sky. One frame holds both.

    Moonlight

    The moon is high enough to cast shadows of its own, west this time. Thirty seconds at f/4, ISO 400, and the yucca draws itself on the sand again.

Where we meet

In the lot at the White Sands Visitor Center on US 70, 15 miles southwest of Alamogordo. We drive Dunes Drive together, about eight miles, and walk in from there. 275 square miles of gypsum, the largest gypsum dunefield on earth, and I know where the ripples were last weekend.

From El Paso’s airport, about an hour and three quarters. From Albuquerque, about three and a half hours. Arrive the night before a sunrise.

Questions

What time zone are the times in?

Mountain Time. MST until Sunday, March 14, 2027, then MDT (one hour later on the clock). Every time I text you says which, and I add yours if you’re booking from somewhere else.

How do you get in before the park opens?

Commercial workshops in the park need a permit, and Gypsum works under a commercial use authorization from the National Park Service. On sunrise mornings we enter early under its terms. You still need the park’s entrance pass for your car, at the gate or online.

What if the missile range closes the road?

The park sits beside White Sands Missile Range, and during some tests US 70 and Dunes Drive close for a few hours. The closures are posted ahead. If one lands on your morning or evening, I move you to the next one or refund you.

What if it’s cloudy?

A thin high cloud is a gift: pink sky, soft shadows. A solid overcast flattens everything, and then you choose: come anyway at half price, or move to another date. Strong spring wind (March and April) can blow gypsum; I’ll tell you the night before.

I only have a phone. Is that enough?

Yes. About a third of each group shoots on a phone. A tripod mount for it helps at moonrise; I have two.

How fit do I need to be?

You need to walk a mile and a half on soft sand and climb a dune or two. We go slowly; nobody runs for the light because we’re already standing in it.

Where do I stay?

Alamogordo is 15 miles away and has plenty of rooms. Las Cruces is 52 miles, El Paso’s airport about an hour and three quarters.
