| Many of the Great Basin Rattlesnakes shown on this page were found in Nevada because I don't yet have pictures of the "pure" subspecies from Oregon, Washington, or Idaho. Part of northern Nevada is included in Alan St. John's excellent field guide "Reptiles of the Northwest" so that's another reason to include them here. They are also found on the Southwest page. Pictures of the subspeces found in California in an area also shown in St. John's book are found in the California section of the website. |
