Along the side of the road are these weird mustard colored lengths of corrugated drainage pipe that seem to funnel toward the roadside. Where they meet is a culvert about 10” in diameter with a slotted grate open to the road surface. There are three or four of these setups. It seems the long toed salamander is endangered. He ranges from the hillsides on one side of the road to the lakes on the other side. Hence, the mini underpasses. Not as flashy as the predator under and over passes we have seen but no less amazing.
