Map of Southern Utah in 1857, highlighting the Mountain Meadows area including the Wasatch Mountains and Colorado River. This is a cropped version of <a href="//commons.wikimedia.org/wiki/File:Mountain_meadows_map5.jpg" title="File:Mountain meadows map5.jpg">Image:Mountain meadows map5.jpg</a> in the more appropriate <a href="https://en.wikipedia.org/wiki/PNG" class="extiw" title="en:PNG">PNG</a> format. Note: This map is not accurate, although I can't speak to how effectively it locates the Hamblin house (now a museum in Santa Clara) or Mountain Meadows. Washington, St. George, and Santa Clara are all shown 10-20 miles east of their actual locations. Notice that Santa Clara, not St. George, is shown to be on the Virgin River.
