Like the northern extent of the Oregon
Cascades, the southern half has even less rugged of a profile
when compared to the Washington end of the Cascade Mountains,
but still has an equitable density of waterfalls throughout. The
Southern Oregon Cascades region consists of land from the Row
River basin south to the California border, and west from the
Interstate 5 corridor to the Deschutes River and Highway 97.
Douglas County -
Along Hwy 138 has the most
waterfalls in southern Oregon.Jackson County -
The majority of waterfalls in Jackson County are around Union
Creek and Prospect areas. As you travel south the waterfalls
start diminishing in quantity and size. There is less snow and
rainfall in Medford/Ashland area verses the Roseburg areas.
Josephine County -
The Majority of falls
are on Lower Rogue River and Siskiyou Forest areas. Same approx.
snow & rainfall as Medford area.Coos County -
You must travel inland north from the coast. Many are very hard
to reach. The southern coast region does not have waterfalls.
the primary geologic feature of the southern
cascades is Crater Lake, the massive remnant of the explosive
history of Mount Mazama, once Oregon's tallest mountain.
Radiating out from the Mazama volcanic group is evidence of
widespread volcanism that has produced some of the largest, most
scenic and most impressive waterfalls in southern Oregon. But
not only has this violent past resulted in the base geology to
produce waterfalls, but the porous bedrock has allowed hundreds
of springs and aquafirs to burst forth from the ground, ensuring
even flow in many of the region's largest rivers for most of the
year. Some of these springs even gush out of the ground forming
waterfalls immediately as they emerge. Fortunately this
landscape is sufficiently isolated from major cities such that
the majority of the region is undeveloped (logging aside)
despite the fact that only a fraction of the land is actually
federally protected. Waterfalls develop

change. Energy from the plummeting water creates a plunge pool
at the base of the waterfalls, eroding a cavity in the softer
underlying rock this process undermines the resistant layer,
causing it to break apart, piece by piece, along the cracks and
fissures. Through this process, waterfalls gradually migrate
upstream. Over the course of thousands of years, this movement
can be a few feet to hundreds of feet.
1. Stay on the trail to protect fragile
2. Pack it in, pack it out- Leave nothing behind.
3. Be sure your matches/cigarettes are completely put out a bear
rock or in mineral soil and dispose of property.
4. Wash with
biodegradable soap, away from open water..
