Walking around on dredger tailings like the ones on Mississippi Bar, you see an awful lot of rocks. Most of them are pretty unremarkable at first glance; of course, you could spend a lifetime sifting through these rocks and finding interesting colors and shapes. Traveling over the rock piles can be tricky — if you don’t watch your step it’s easy to lose your balance or even twist an ankle. But I will say it’s good exercise! And you never know what you might find.
