Daily Postcard: A view of a felsenmeer along the slope of Redondo Peak in Valle Caldera. Felsenmeer rock fields are exposed rock outcrops or scree fields that make up only about 1% of Valles Caldera National Preserve’s land area. A felsenmeer is a unique environment characterized more by rocks than by plants. Growing conditions for plants are harsh because the poorly developed soils don’t hold much water. Courtesy/NPS/R.
