The Christmas Valley Sand Dunes Area of Critical Environmental Concern (ACEC) in south-central Oregon is the largest inland shifting sand dune system in the Pacific Northwest. It is a popular destination for off-highway vehicle enthusiasts with nearly 8,900 acres of the Sand Dunes site open to vehicle use. Nearby, the Lost Forest Research Natural Area is an unusual stand of ancient ponderosa pine forest, the remnant of a forest that existed in a cooler and wetter age.
