How to tell if ice is "thick enough"?

[albinotrout]

From your pic looks like a critter has already crossed the lake. Best way to determine ice thickness is to drill a hole. If no auger present and unsure on thickness, step onto the edge of the ice to see if it holds your weight. Do t go out too far until you are sure it will hold you up. Some people throw rocks onto the ice, which is frowned on by many for the rocks will freeze in the ice and if someone is drilling a hole and hits said rock it can damage blades.
