The search for hiker Eric Sears and the deaths of two searchers in a traffic accident have spotlighted a quiet but crucial group: search and rescue teams.

These people - many of them volunteers - do dangerous work under difficult conditions. They brave mountain cold and desert heat, combing treacherous terrain for lost hikers, flash flood victims or people who have just disappeared.

They can be called out at any time in any weather, no matter how inconvenient, and routinely risk harm to themselves in order to help others. They earn the reward of saving lives, but also face the grim task of recovering the dead.

Given the large swaths of wilderness in Riverside and San Bernardino counties, search and rescue teams are essential. But that doesn't mean the public should take their work for granted, or only notice them when a rescue or tragedy occurs.

These teams provide a safety net for everyone who explores the mountains and deserts. For that, they deserve appreciation.
