This Cross Reference Summary shows comparisons between 2005, 2004, 2003, 2002, 2001, 2000, and 1999 Expedition itineraries by indicating several highlight features for each. It is presented to assist crews in selecting itineraries and to assist veteran Philmont campers who have become familiar with the Expedition itinerary numbers and routes. All information is from the (a) Treks 2005 Itinerary Guide, (b) Treks 2004 Itinerary Guide, (c) Treks 2003 Itinerary Guide, (d) Treks 2002 Itinerary Guide, (e) Treks 2001 Itinerary Guide, (f) Treks - 2000 Itinerary Guide, and (g) 1999 Advisors Guidebook & Philmont Itineraries PEAKS books.

In 2000, Philmont did a major overhaul. Though all of the 1999 itineraries were preserved with similar routings, almost every itinerary was given a new number in 2000. The objectives of this major overhaul in 2000 were to: (1) have the difficulty rating increase as the itinerary number increased; (2) accomodate eight new itineraries added since 1997; (3) use new technology to reflect true mileage more accurately; (4) modify itineraries to avoid camping above 9000 feet until after the 3rd day to ease altitude acclimatization.

Since 2000, minor changes and adjustments have occurred each year and major changes are rare. The Ponil Complex fires in June 2002 caused significant and major itinerary changes for the 2002 season. New "Fire Modified" itineraries were created, sometimes changed on a daily basis, and continued to be used for much of the summer, especially for routes in the North and Valle Vidal regions. The 2002 itinerary listings shown here are as originally planned and published in the Treks book. In 2003, the number of itineraries in the North and Valle was reduced as a result of these fires, and five North and Valle itineraries (19, 20, 25, 31, 34) were completely changed to the South and Central. Two (19 & 34) have since moved back to the North and Valle.

Crews should always (a) use the Philmont topo maps for planning their routes and (b) discuss the route options during their briefing at Logistics upon arrival.
