The Double Cone Quarterly
Window to the Wilderness
Winter Solstice 1998 || Volume I, Number 3

Test your Topographic Know-how

Well, last quarter's Map Mania puzzler was obviously a little bit easier than the one before it. The issue wasn't out a week when in came the winning ticket, with all the locations correctly placed. As promised, David Rogers can now boast a copy of the Wilderness Act Handbook of 1998 as part of his library, and there's another of the same offered up for the winner of this issue's contest.

But first, the answers to last quarter's Map Mania puzzle:

The Snippet: 

  • "Old" Indian Valley Camp, near the intersection of the Marble Peak and Higgins Creek Trails
The 3-D DEM: Tassajara Hot Springs 7.5' Quadrangle
  1. Lost Valley Camp
  2. Higgins Cabin Site
  3. "Old" Indian Valley

OK, here's the game: both graphics below correspond to actual places somewhere within the Monterey Ranger District of the Los Padres National Forest. The first one is a small piece of one of the various USGS 7.5 ' topographic quads which cover the area. The second, larger, graphic is what is called a digital elevation map (DEM) which is essentially derived from the information on the 7.5' quads, only rendered in 3-D. To grease the skids a little we've given a sort of hint in that the snippet lies somewhere within the topography covered by the DEM, and if this doesn't give it away look to the Lost Trails feature in this issue for yet more help.

Here's what we ask of you:

  • For the small topo snippet, identify the location of the segment any way you can.
  • For the larger DEM, name each of the geographic features designated by the numbers 1 through 4.
When you've got all this figured out, send your findings by email to  Gordon Johnson , with the first one to correctly identify all the locations being the Big Winner. So what's in it for the Big Winner, you query? Well, Gordon has generously offered up an item from his own personal library: a brand new copy of the super-informative Wilderness Act Handbook of 1998. This classic handbook is invaluable for the wilderness advocate. It contains a section-by-section explanation of the Wilderness Act, including the law in its entirety, with an analysis of subsequent legislation that has influenced the designation or management of wilderness. Important wilderness management issues are included. The Handbook also contains short milestone references to significant wilderness events through 1998 and a brief description of The Wilderness Society mission and regional structure. As you can see the stakes in this game are high, so pull out all those dog-eared topos of yours and get to work!
OK, think you have it all figured out? Email your answers to Gordon at
