Wide brush strokes painted north and south. They were lines on a map of Wyoming already full of lines indicating rivers, mountain ridges, highways and interstates. But these brush strokes â wider than any of the others â illustrated where the Platte Valley mule deer herd migrates, threading east of the Sierra Madre and west of the Snowy ranges.
Many of the lines stopped abruptly at the border between Wyoming and Colorado. Except, of course, the deer themselves donât stop there. They keep wandering on for 30 or sometimes 40 miles following better food as snow piles in late fall and melts in the spring.
