Worth knowing

Why the canyon floods so fast

Old Bisbee was built up the walls of Tombstone Canyon and Brewery Gulch, which act as natural drainage channels. Runoff from a single cloudburst converges on the narrow streets of the historic core. The old Copper Queen drainage 'subway' and a New-Deal system of hundreds of check dams and masonry walls are what keep the business district from washing out — but they can be overwhelmed.

When it matters most

About 10 of Bisbee's roughly 18 inches of yearly rain falls in the July–September monsoon. Storms build fast in the afternoon and evening. If you live or park on a low canyon street or near a wash, watch the sky in those months and have a way out that doesn't cross moving water.
