Erik the Black's Colorado Trail Atlas 2nd edition is now available for pre-order. This edition includes the Collegiate West route. The estimated ship date is the 1st of May. See his website for details etc.
FYI, I'm not in any way affiliated with Erik the Black. But, I have used his products for the CT as well as what he has available for the PCT (3rd edition) and have found them very useful. His CT Atlas (1st edition) was the sole resource I have used to complete the CT.
