Carbon Glacier Trail Professional Review and Guide
"Though the trail is lovely, it’s not exactly a thrill—not until you reach the end of the route. There, you’ll find yourself swinging on a cable suspension bridge and cooling your heels on an actual glacier. Getting to those highlights, you’ll trek along an old miners’ road paralleling the Carbon River upstream.
This frothy river boasts some serious white water, but it’s not because of the rapids (which are generally small and not too frothy). Rather, the whiteness of the water comes from all the powder-fine silt ground up by the moving glacier. This water, known as “glacier milk,” is deathly cold (remember, it’s melted glacier ice from just a few miles upstream), so regardless of the heat, steer clear of the river itself."
