These photos came throught on an email the other day and thought they were pretty impressive. Especially the one with the 2 mountain lions walking side by side. The photos are from a motion activated camera monitoring critters using one of the wildlife crossings installed on the improved Highway 93 by Ravalli, north of Arlee. Arlee is about 20 miles north of Missoula, MT.
The tunnels effectiveness were researched by UM biology Professor Kerry Foresman. You can read more about the research here. The tunnels have also been installed on Hwy 93 south of Missoula.
