Spring can try the patience of Wood River Valley trail runners, mountain bikers and other backcountry trail users.
In an average year, most area trails aren't snow and mud free—and therefor open—until at least late-May, said Renee Catherine, trails coordinator for the Sawtooth National Forest's Ketchum Ranger District.
With below-average snowfall during the 2006-2007 winter, many of those trails are already open, Catherine said Thursday.
"We've got this whole labyrinth of trails open," she said.
Still, many trails remain snow-covered and muddy, and deciding whether to ride a trail or not comes down to one thing, Catherine said.
"If you leave a muddy track, turn back."
The difference between muddy trails in the summer and the spring is distinct. In the spring, inch-wide lateral bicycle tracks can lead to water channeling and long-term rutting that is difficult to correct.
"Right now we've got saturated conditions," Catherine said. "Now is the time to make or break them."
Fortunately, most trails currently unsuitable for use are signed as such by Big Wood Backcountry Trails volunteers.
This time of year, patience is definitely a virtue, she said. Within several weeks, most area trails now closed should be open and ready for use.
The Forest Service doesn't use enforcement or a special closure to keep users off sensitive trails in the spring.
"It's definitely an honor system," Catherine said.
