This was one of those serendipitous occasions when a bend in the road yields a magnificent sight. Calera is a ghost town so obscure, you can't find it on maps, and I'd certainly never heard of the place. The jewel of this little place at the foot of the Davis Mountains is this little chapel, Mission Mary. I'm not sure how old this church is. A brochure I picked up inside said it dated from about the turn of the 20th Century and was one of about 40 mostly-Hispanic Catholic missions served by the same priest. Originally of exposed rock construction, Mission Mary was dryalled over in the 1930s and continued to function through World War II. The church fell into disrepair until 2003 when it was restored. It's now kept unlocked with visitors invited.
