Was water before it was cool… While ice on a lake may look like it's frozen solid, the ice might be thinner than you think. Always use caution when walking around the edges or on top of frozen lakes. It’s especially important to be careful near inlets and outlets, where moving bodies of water weaken the ice from below.
