Chocolate Falls in Arizona: Photographing a Flash Flood on the Little Colorado River
Grand Falls Goes from a Trickle to a Raging River
The Little Colorado River, which begins high on Mt. Baldy in eastern Arizona and runs -- sometimes just barely -- 315 winding miles to its junction with the mighty Colorado in Grand Canyon, is a very moody river. One minute, you might step over the wee ribbon of water and, the next, step back! You don't want to get caught in that boiling, muddy torrent.
Nowhere can the Little Colorado River (also known as the LCR) be as dramatic as it is where it drops down the huge natural stairway at Grand Falls, otherwise known as "Chocolate Falls," located 30 miles northeast of Flagstaff, Arizona. And that's where I was in August of 2005, when I took this photo. That's my red truck up there by the overlook, not far from a spot where you can sometimes drive right across the river. Not so on that day!
And I've been there many other days since, during other flash floods and even when not a drop was flowing where the falls had just recently been and would soon be again. I've been to this hidden, remote desert beauty as a regular outdoor enthusiast and as a Search & Rescue team member on a missing person search, which you can see and read about below, along with other information about visiting Grand Falls.

About Arizona's Grand Falls
An amazing site to see in the Painted Desert
Grand Falls is located on Navajo Nation land, at the southwest corner of the Reservation about a 45-minute drive from my home in Flagstaff. It's often referred to as "Chocolate Falls," for the reason you'll see in the photos and videos on this page: MUD!
When Do the Falls Run?
At 185 feet tall, Grand Falls is actually higher than Niagara Falls. And unlike Niagra, which is a major torrent year-round, Grand Falls runs the gamut from bone dry, like you see in my photo here, or merely a trickle during some winter and summer months to a raging force of nature during spring runoff from the snowy mountains to the east and after heavy monsoon season rains later in the year.
I can't give you exact dates or timeframes for when the water will be running high. The best I can do is point you to the USGS website to see the current conditions for the Little Colorado River near Winslow, AZ. As mentioned, your best bets for catching the falls at flood stage are in late spring and during monsoon season (roughly early to mid-July through late August / early September), but you'll want to check the USGS site to be sure before you go.
Update: It's March now, and Grand Falls is at its peak from snowmelt. See Fleeting Falls, the Area's Biggest Waterfall is Flowing Again from the Arizona Daily Sun.
The Formation of Grand Falls
This impressive waterfall was formed about 150,000 years ago, when lava from a nearby volcanic eruption from what is now Merriam Crater flowed into the canyon and blocked the river. The water then had to find a new course around the lava dam and back into the canyon, creating this cascade in the process.
Be Cautious and Respectful of the Land When You Visit
Grand Falls is quite isolated but well worth the long and sometimes dusty drive from Flagstaff or points east. Regular passenger cars can and often do make the trip to the south side of the river, but once the road turns to dirt, it can get washboardy. So drive slowly and don't attempt to actually drive across the LCR in a passenger car. Don't attempt it at all, high-clearance 4WD or not, when the river is running fast and high. (You can see what the road out to Grand Falls looks like in this photo.)
There's no charge to enter the Navajo Reservation and visit Grand Falls, but there are no services for many miles either. Be sure to keep the area clean, pack out your trash, be on the lookout for roaming cattle and desert wildlife, and don't get too close to the edge. There are some big cliffs with unstable rock and slippery mud along the banks. And there's no cell phone service to call for help if someone runs into trouble.
That slippery mud I was talking about? This guy got a bit too close to it and needed a few hands out.

The Little Colorado River's Highs and Lows
More Photos from that Day - I was covered with muddy spray after taking these pictures....
You could hear the sound of large boulders being moved by the incredible force of the water.
Grand Falls on a Very Different Day - I returned to Grand Falls when the LCR was running much, much lower and took these photos....

Walking on Grand Falls - Find out why we did this below....
Search and Rescue teammates and I searched different levels of the falls soon after a flash flood, when the falls were once again just a trickle. We were looking for a missing person who may have gone over the edge.
You can read about this SAR mission and see more photos from Grand Falls and further down the Little Colorado River in my blog post, Searching for Justin.
This may be a no-brainer, but PLEASE don't attempt this -- "walking on Grand Falls" -- when it's running. Just, you know ... sayin'.
Hiking to the Bottom of Grand Falls
You've driven all the way out there, so explore some more if you're able.
As you're facing Grand Falls, if you walk along the rim to your left -- to the west -- you'll come to a short, rough trail that leads to the bottom. That's where we're going in this photo here.
The trail from the overlook leads to the Gauging Station, then turns to the right and takes you to the bottom of Grand Falls.
Watch your step as you descend. There's one short downclimb along the way, but you'll be fine if you take it slow and use your hands.
Please don't go down there when the falls are running high. We don't want to have to look for you downriver.
At the bottom of the Little Colorado River Canyon, hiking towards Grand Falls
There's lots of cool exploring to be done at the bottom of the LCR canyon and base of the waterfall when the water is low, but you're sure to also see an interesting variety of flotsam and jetsam that's been washed downstream and caught by rocks, mud and vegetation. Be careful of broken glass and other sharp objects. On the other hand, you might just find some treasure too!
Grand Falls in Motion
Video footage of the LCR's Lows and Highs
Running Dry - Not too many people shoot video here when the water isn't actually flowing.
I haven't either (yet). And I searched and searched for footage showing a dry, still or barely flowing Little Colorado River at Grand Falls. This is the only video I found that shows -- briefly on fly-by -- a dry waterfall.
You'll also see footage as the helicopter flies downstream above the LCR, which still has water in it.

Video: When the Chocolate Water Runs High - A Grand Falls Flood
This video, taken during first week of August 2010, shows the Little Colorado River at Grand Falls when the water flow was about 1800 cubic feet per second. The flow was even greater a week earlier, the flooding due to a large amount of monsoon season rainfall in Eastern Arizona.

Dusty and flat, but you don't need 4wd
- Take US 89 north, 1.8 miles past the Flagstaff Mall, and turn right on Camp Townsend-Winona Road.
- Drive eight miles, then turn left onto Leupp Road. Follow Leupp Road northeast about 20 miles.
- Just past the Navajo Reservation boundary, turn north -- left -- between Mileposts 5 and 6 on unpaved Indian Road 6910. (There may still be a Grand Falls Bible Church sign near this turnoff.)
- From here, drive 9.4 miles, and after passing Indian Road 70, a series of side-by-side dirt roads veer off to the left before reaching the Little Colorado River. Take one of these to the picnic area at the top of the falls. (If you come to the Little Colorado River crossing, you've gone 0.4 mile too far.) You'll need to park, get out and walk a short distance to actually see the falls.
From I-40 East
Take Winona Exit 211, 14 miles east of Flagstaff, and drive two miles on the Townsend-Winona Road. Then turn right on Leupp Road to the Grand Falls turnoffs, following the directions above.
- From I-40 Exit 245, 46 miles east of Flagstaff, take AZ 99 to Leupp Road.
From Kykotsmovi on the Hopi Indian Reservation
- Take paved Indian Route 2 southwest, 49 miles to Leupp Road and follow the rest of the directions above.
A Map to Grand Falls - Zoom in at least three time to actually see some very rural roads between Flagstaff and the Falls
You'll need to click on the map and drag it up to see the roads you'll take from Flagstaff, once you zoom in far enough.
Yep, there's a lot of wide open country out there!
