Bullion Creek flows into the town of Marysvale, coming out of a canyon where mines did in fact produce a significant amount of gold.
From US Hwy 89 in the middle of town, follow Center Street west into the canyon. Park at the bridge just below the old miners park and then hike along the north side of the creek. You'll soon come to an overlook where you can see the stream plunge down a two-step waterfall.
Hike to the pool and you'll feel the power of the stream as it comes down a 50-foot cliff above you and then tumbles down a dizzying precipice into the canyon below.
