Disclaimer: although I have made a reasonable effort to cross-check my work and believe the list to be accurate, some flaws in the data may exist, either of my own, or from other sources, like USGS datum. Furthermore, I most certainly missed some passes and have added over 120 since the first publishing of this list on my site; there are passes on some maps that do not exist in the USGS datum, and some that don't exist on other maps, so if you know of any, please provide the information to me, and I'll add it to the list. I decided, after exploring the accuracy of the USGS data, to not post links to TopoZone because in many cases it's as far as a few hundred yards off. The 120+ new ones have accurate lat/lon information either from direct GPS readings or manually locating the passes on 10K or 25K USGS topos. Most of the "pass type" data is combined from various sources, personal observation and USGS. I was recently informed that Bob Bump of the Colorado Pilots Association deserves credit for the early work on the pass type and ownership data. Thank you Bob! Thanks too to Randy at Pass Bagger for posting his passes spreadsheet and informing me about Bob. The remaining data is either in the public domain (such as the base USGS datum) or is my own work (many corrections, the CA&G references, etc.). I make no claim for the currency of public/private land information, as this changes without warning. You are solely responsible for your conduct and safety should you choose to visit any of these areas. Having driven or hiked over 130 of these (as of February, 2012), I can tell you that this activity carries a fair risk of harm, so proceed with caution, and I cannot be held responsible for the outcome of your travels. Please enjoy and be careful.
