I also like this one: "Route sketch of the march made by Troop "I" and "M", 9th Cavalry" to Sequoia national park and Grant Grove in 1903. You can read about it here.
I also have two versions (dated 1896 abd 1907) of the map "Sequoia and General Grant National Parks and the Sierra Forest Reserve" that look like the came out of a report, and a "Map showing wagon roads and trails in Territory embraced by Sequoia and General Grant Parks, etc." that looks like it came out of a department of the interior publication 53 2, whatever that means :)
