These photos were taken at the Cathy Fromme Prairie Natural Area, just south of Fort Collins, Colo. This acreage, which has never been plowed, is bounded by two major roads to the east and west and by housing developments to the east and north. It’s lovely country, but the traffic noise is omnipresent. When I had walked about 15 minutes, it began thundering persistently, so I backtracked to the parking area. I didn’t get photos of the many flowers still in bloom, many of them very small and easy to overlook.
