Smoke has been fairly thick in the valley, and across western Wyoming over the past several days and the source may not necessarily be from local fires. While small fires continue to burn in the two national parks and on Bridger Teton National Forest, wind currents are carrying a majority of the smoke that is reaching us from fires in northern California, northern Nevada, and across southern Idaho. 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. The public’s best defense is to limit exposure as much as possible and to limit heavy exertion if the smoke is causing respiratory distress.
