The pass over Donner Peak in Northern California is known as Donner
Summit and has been a critical route across the Sierra Nevada Mountains
for centuries. First it was used by Native Americans, then early
settlers, and then emigrant wagon trains such as those used by the
ill-fated Donner Party, in whose honor the region is named. The first
transcontinental railroad in the United States and the first
transcontinental highway in America both made use of the Donner Summit
route to gain access to California; even early aviators used a beacon at
the Summit for guidance across the Sierras. Most of the communities and
points of interest along the railroad and highway route up and over
Donner Summit are covered in this book.
