The Arizona-Sonora Desert Museum will re-open at 11 a.m. today. While the source of water loss is still unknown, water is flowing into, and collecting properly, in the Desert Museum’s reservoir. Food service will be limited to pre-packaged items for the remainder of the day. All other activities are back on the normal schedule. Thank you.

The Samaniego Hills are just a few small round bumps on the landscape. On their lower eastern bajada at the edge of the Avra Valley the deep soil supports some very large ironwood trees. Saguaros are rare here but they too tend to be huge.
