Thank you Latitude Adjustment for pointing out that dive detail. I just entered San Carlos as a "Dive Site" in the DiveBubby.com search and found the inland site at San Carlos, which is in the state of Coahuila according to my daughter. This result is very similar to what you have described in your comment. However, when I entered San Carlos in the "City" box and Sonora in the "State" box, I find results for six dive sites in seven entries. All have names of dive sites that I recognize as places where I have been diving many times. For example: DiveBuddy.com members, AirOn, ScubaKristen, and Scooby450 all claim to have visited "Deer Island" (a.k.a. Isla Venado). To my dismay though, the Island DOES NOT appear on the map below, but the place pin is quite accurate in its placement on the best site at this San Carlos area island. I fully recognize the comment description for the southeast corner of Isla Venado. Soon I will upload pictures from my portfolio and details about the canyon on the southwest side of the island. Also located in the results for the "City" of San Carlos in the "State" of Sonora were: Eagle Rock, Martini Cove, San Antonio Point, 2 entries at San Pedro Island/Seal Island (Note: there are NO seals there except for the USN type "Support the Troops", just fun loving friendly sea lions) (a.k.a. Isla San Pedro No;asco) and an entry Titled "Sea Mound" (a.k.a. Sea Mount) visited by members; pinkladydi, and AZDIVEPRO. In closing, from an environmental point of view, the fact that so few people visit here is probably part of the reason why many of the area dive sites are so "take your breath away" BEAUTIFUL (maybe not a good expression for a dive blog). Please come visit, but please don’t make a mess, and if you do, clean it up before you leave. Take only pictures and leave only bubble, and if you feel the need to harvest seafood, PLEASE, NO MORE THAN what you plan to eat for dinner tonight!!!!!!!
