Shop is in a deep gorge that drains Alum Cove and other points around the junction of Hwy 16 & 7 just east of Deer. It’s a classic north facing drainage with multi-sized boulder drops and excellent gradient. It takes a toad strangler to get it up for a good run. I think the first descent was pioneered by Randy Jackson, Rob Sanner and maybe Wade Colewell? I don't remember for sure but maybe Randy can fill in that memory. I really appreciated the classy names they gave for the significant drops on the creek. They are in order - Hypermart IV, Blue Light Special IV, Checkout Line IV+, No Refund III, and Thanks for Shopping IV. The takeout is in downtown Parthenon, Arkansas.

This is Steve Daniel running Hypermart. From this perspective the drop looks fairly innocuous until you realize the photo is taken directly atop a massive boulder that is severely undercut. There are two or three boulder drops just upstream of this drop from where you can sort of boat scout. The green slab or what's left of it from the slot feeds you directly into the undercut. There is a rolling curler that when hit correctly will typewriter you to the left away from harm. My memory is the key was to punch the hole then relax and draw left and let the curler work.
This is Randy Jackson running the same drop. Note that he's paddling the vogue boat of the time, one of them fancy new Dagger Crossfire's. When the design came out most of the old guard said it was dangerous to have a asymmetrical design with a low volume stern.

The rest of us were paddling classic long boats. At that time I had an Infinity Quantum. I think everyone else was paddling a Dancer, except Steve Daniel. I believe he had just gotten one a new Perception Corsica S which was also a new boat design that was a shorter higher volume version of the Dancer. This is Wade Colewell running Blue Light Special. This is one of the hallmark drops on Shop Creek. It’s a blind entry around a boulder into a pretty tall drop.

I remember this day pretty well. It was warm weather and laughed and carried on a good long while at the takeout.

You are correctly observing that Steve Daniel has no legs. He's the author of Texas Whitewater. I was pretty worried that if we were able to get him into Shop we would never get him out if we ran into trouble. He drug his own boat to the bottom. It’s a steep and rugged trailed about 3/4 of a mile down in total. He's a PhD of Philosophy at Texas A&M and once he was in the boat he was a master paddler.
Hope you enjoy this little trip down memory lane. I also hope Randy Jackson can fill in some of the important details I've forgotten.
