Throughout this guidebook, Google Maps is exclusively used for both the overview and interactive maps on each page. With the interactive maps, red lines are used to delineate the most common ascent routes, blue lines for descent options, a “P” to indicate where to park, a yellow pin to indicate a unique hazard or label a map feature, a green house to mark huts, and a snowflake to label peaks not named by Google. Most major descents in an area are marked, but many are not to avoid cluttering the maps. On the interactive maps, clicking on a line or icon brings up a pop-up bubble. This bubble has the route’s name and sometimes brief information associated with that line. In the lower part of this bubble, Google provides the distance of these lines as drawn on the map. But it is important to understand that these distances are unreliable, and in many instances incorrect, so disregard Google’s distance value and refer to the distances in my text. This inaccuracy is especially true in areas with multiple ascent routes, where intersecting routes will show the mileage only up to the intersection with another route, not the total distance (example: Castle Peak).
