This map was created by using the kml file for parcel locations downloaded from the BLM website and the park boundaries in shp format downloaded from a public government ARCGIS siite and converted to kml for Google Maps. This is not an official map from either BLM or NPS, but its data comes from those sources and is consistent with that available from each entity separately.

You can zoom in on the lease parcels, click on them individually, and see a bit more info about them.
