Summer Travel Regulations go into effect today for the Teton Basin Ranger District of Caribou-Targhee National Forest. Local conditions are slowly becoming suitable to support vehicle traffic on most roads and some trails without causing resource damage. At the same time,forest officials say cross country snowmobile travel can still occur at higher elevations where there is plenty of snow. District Ranger, Jay Pence points out, however that due to budget constraints, many of the forest roads in that district will not be graded this year, and themain roads or roads that get the most use will only be graded once. Therefore, he says the condition they are in when they come out of the snow may very well be the condition they remain in through the summer season. Pence also points out that the district is closed to cross country motorized use.
