WASILLA - While many Alaska lakes are newly frozen, officials are warning residents to be careful when crossing.
Cliff Silver, the chief of the Matanuska-Susitna Borough's water rescue team, says the ice should be at least 8 inches thick before anyone tries to drive a small vehicle on it.
He says that's still too thin for him, and he adds many lakes have hot spots where the ice thins out.
The best way to gauge thickness is to drill a hole with an electric hand drill.
