A project is rarely ever actually completed, so the question of when to release a survey can be challenging. However this is the first time in the Crusader project that all the known passages are on the survey, so it seems like a logical time to release what we have.
Below is a link to a high res jpg and a pdf version. Please see these as an invitation for them to be laminated and carried with you on your trip in to see the new stuff. Bear in mind that only the thin and determined will fit through the Crusader Squeeze, and it'll take some close attention to the survey and website reports to find your way there. Good luck!
UPDATE 2016: Following ongoing requests, we have created an annotated map showing how to navigate your way to the Crusader extensions, which can be downloaded here: Crusader Directions Map
