Where is all this smoke in the valley coming from? While there are fires burning on the Bridger Teton National Forest south and north of Jackson Hole, they are not really putting up any significant smoke. However, southern Idaho has seen a number of fire starts, and predominant winds are from the direction of several of those fires. Maps tracking that smoke from the national weather service indicate much of the intermountain west is receiving various amounts of smoke as well. Forest officials point out that smoke exposure can temporarily cause burning eyes, runny nose, scratchy throat, headaches, and illness. However, these symptoms usually disappear soon after one leaves the smoke.
