Al said "You approach the pool from below over a steep, boulder-studded rapid that drops a good 3 feet in 20 yards or so. It lays beneath a 70 foot high cliff, water-streaked and stained dark gray. Big boulders clutter the pool on an otherwise bedrock bottom, and it is smooth water that appears deep, though it's only about 3, maybe 4 feet at the deepest. The trees arch over the water opposite the bluff, and blooming dogwoods line the top of the cliff. It's achingly beautiful."
Great descriptors, I hope you put it to canvas.
