It climbs Snoqualmie Pass at 3,022 ft and Lookout Pass at 4,711 ft, where the weather at the summit is not the weather on the approach.
Mile markers count from each state's western line and start again at the next one, which is how most states number their exits as well. They are measured along the same road geometry these pages draw, so they land within a mile or two of the posted markers. A toll road that runs its own continuous numbering is the exception — on the New York Thruway the posts continue from New York City — and there the figure is how far into the state the place is rather than the number on the sign. Distances are measured state by state, never across a gap.
