Rock or Ice Cream? Erosion Tales

I’m fascinated by erosion patterns in rock that make solid rock look like ice cream that has been scooped with a spoon or carved with a giant fork. So, I was transfixed by this “fork action” on the red rock in Sedona.

Seeing this horizontal pattern in the sandstone along Oak Creek made me wonder how Nature made this carving. So I asked my geologist friend, Steve Austin. Location: West Fork Trail, Sedona, AZ, USA.

It’s amazing what Steve can tell us just by examining this photo and knowing its location. He said, “The sandstone has horizontal layers but also has inclined layers internally (25 degrees). The cliff shows these inclined layers because rockfall has sculpted the surface. These inclined layers were formed in underwater sand dunes by flow velocity of 2 meters/second.”

Wow! That’s why they call Steve “Mudflow Man.”

Crossing Oak Creek 26 times

Both Charlie and I slipped and got one shoe wet while crossing Oak Creek, hiking the West Fork Trail in Sedona. Only one slip for each of us was pretty good considering the rocks and logs we needed to balance on while crossing the ice cold water. I snapped a few candids with my new iphone 11 Pro Max as we crossed a few times, to show how tricky it was.

With his Steeler hat and jacket, Charlie is ready to talk NFL football with anyone he meets, while climbing boulders and trying to stay dry crossing Oak Creek.

You hope that the rock you step on is sturdy and won’t tip over, sending you and your backpack into the water. Crossing Oak Creek on the West Fork Trail, Sedona in November.

After 5 hours of hiking and plenty of quad and knee exercise, we were a bit tired, but we paused and made a strategy for one of the last crossings of the day on West Fork Trail.

Rewards of West Fork Trail

Sedona’s West Fork Trail is described in the guide books as iconic with towering cliffs and 13 stream crossings as you follow Oak Creek for 6.4 miles round trip. The elevation change is moderate (245 ft.), so I considered it doable with camera equipment on my back.

It took us 3.5 hours to reach the end point, as I stopped for photos so often, but the exertion was well worth it. You know you have reached the end when you can’t go further without getting wet, and in November it’s too cold for that!

A mirror-like reflection was the reward at the end point of the West Fork Trail. Sunny conditions were perfect for the hike, as rain can create dangerous flash floods, and snow would make the hike too slippery.

The cave like erosion you can see along the left side of the creek reminded me of “the subway” in Zion National Park created by the Virgin River. I had to explain myself to my husband after exclaiming, “there is the subway!”

I find myself fascinated by the power of moving water that erodes rock over time. Are you?
