In artist Dan Bell's world, the Pacific Ocean is the Sundering Seas, Gondor is Noe Valley and the Haight is Rohan. The 25-year-old re-envisions San Francisco, and dozens of other geographic locations, as Middle Earth.

Everything from Oakland's Lake Chabot to the ordered streets of London gets a Tolkienese makeover in the hands of Bell. The artist draws each map to scale, and with a Middle Earth flourish reminiscent of the maps J.R.R. Tolkien included in his "Hobbit" and "Lord of the Rings" series.

A biologist by trade, Bell is particularly attracted to the national parks. His renditions of Yosemite and Yellowstone look torn directly from Tolkien's notebooks. El Capitan looks exceptionally un-menacing when depicted as three shaded triangles.

When deciding what to draw — he's created nearly 150 maps in less than a year — Bell looks for places with lots of "mountains, forests, rivers and lakes." In other words, the types of landscapes the bard of Middle Earth gravitated towards.

Bell admits he's not the "world's most devoted fan," though he joys Tolkien's works immensely. His attraction to the Tolkien cartography is more a matter of style.

"They seem to suit my artistic ability," he said by email, "which is to say that I have a steady hand and a lot of patience."

Maps are available for purchase on Bell's website here. See a selection of his drawings, and their real-world counterparts, in the above gallery.
