a popular stretch of whitewater on the Clark Fork river about
35 miles west of Missoula, Montana. This map is a general
guide for kayakers and rafters to help them locate the rapids
and the access points, as well as to provide ownership information
on the lands on either bank of the river.
A portion of the Great ide Trail, a series of maps produced and distributed by Adventure Cycling. This route guides cyclists along primarily dirt roads in the Rocky Mountains all the way from Canada to Mexico. The design and text was done by Adventure Cycling. I was contracted to recreate most of the features on these route maps from various sources, the topography was derived from the 1:250k series DEM and then were converted to

of Missoula Valley. The drainage of the Clark Fork river was
blocked by the continental ice sheet as it moved southward
about 15,000 years ago. The lake formed by this ice dam, known
as Glacial Lake Missoula, was approximately the size of modern
Lake Ontario (500 cubic miles), and was up to 2000' deep.
This lake drained in matter of days, releasing the greatest
flood of known geologic record. Evidence in the scoured flats
of eastern Washington indicate that the lake filled and drained
at least 41 times.
