Vulcanism (My RV may be named Enterprise but this is NOT about Spock)

Newberry Caldera is from a massive shield volcano east of the line of volcanoes that form the spine of the Cascades.  Near its center is Paulina and East Lakes (see my last post), Big Obsidian and a number of other volcanic features such as lava flows and cinder cones.  To the north, the caldera spreads out with lava casts, lava tubes and lava flows.  One cinder cone is Lava Butte.  It rises 500' from the surrounding ground and has a 150' deep crater at the top.  The following photo is copied from a photo posted at the top of Lava Butte.  Note the road spiraling up to a parking lot at the top.

From the parking lot you can walk up to a fire watch building at the top of the cone.  From there, you can see into and across the crater and out over the lava field that stretches for miles from the Butte.

Off in the distance, other cinder cones project above the surrounding land.

As barren as the cinder cone appears, life still flourishes.

The La Pine area

I am at La Pine State Park.  The Deschutes River flows through the park.  I can't see it from my campsite, but it is only about 300 feet away.  Nearby, there is a bend in the river with an overlook.

About 15 miles to the east is the Newberry Caldera.  Within this caldera are two lakes, Paulina Lake and East Lake.  East Lake is pretty, and

Paulina Lake is spectacular.

Mount McLoughlin

I just finished a week at the foot of Mount McLoughlin, at Willow Lake.  The view from my window was, to say the least, spectacular.

The lake is, by all indications, a good spot for fishermen.  It was for this particular fisherman.

For me, I saw it more as a palette upon which the colors of the forest and mountain were reflected -

at least when the air was calm, such as at sunset.

To the north are the western slopes of Mount Mazama, the remainder of the volcano that became Crater Lake.  The upper slopes are deep in ancient ash.  When that ash erodes, the result can be remarkable.  Here is one such ash area.  Those two trees are on the far side of the ravine and are perhaps 100 feet high each.  The pillars of ash are perhaps 20~30 feet across and perhaps 100~150 feet high.  I was right at the edge of the near side of the ravine and that soil is crumbly.  I was NOT about to hang onto a tree at the edge and lean out trying to see/photo the stream at the bottom of this thing.  This type of formation is apparently fairly common on the outer slopes of Mt Mazama near the crater.

If you use Google Earth, this ravine can be seen at 42 deg 53.75" N, 122 deg. 15.25' W.  Google Earth says it is about 200 feet deep, so my estimates may be off a bit.

Lava Tubes and the Disappearing River

The Rogue River flows, strong and clear, past the Gorge and into the Natural Bridge area.

There is a lava tube there, into which the Rogue River drops.  The river all but disappears under the ground, flowing through several lava tubes. 

It finally emerges with great force many yards downstream.

Not all the tubes flow clearly.  This one is blocked and the water enters, circulates and exits at the same portal.

Two Waterfalls

The Rogue drops into a boulder field near Mill Creek.

Below the field, the Rogue becomes a very intricate Class 5 whitewater run bracketed on each side by vertical walls about 150 feet high.  Dropping into this canyon below the boulder field are two waterfalls, Barr Creek Falls and Mill Creek Falls.

Barr Creek Falls...

Mill Creek Falls...

Crater Lake

Crater Lake is formed from the collapsed caldera of Mt Mazama.  The resulting lake is over 1000 feet deep and is fed only by rain and snow runoff from the caldera sides.  It is considered to be the cleanest, purest lake in the world.  Right now, in mid-March, the snow there is about 10 feet deep in places.  The blue of the lake has to be seen to be believed.

The outer slopes of the remnants of Mount Mazama feed the headwaters of a number of rivers, among them the Rogue.  About 30 miles from the caldera the Rogue drops into a collapsed lava tube.  The entire river is compressed into a channel that is so narrow that one could almost step across it.  The force of the river pushing through this slot is incredible.

To the southwest rises another, much smaller volcano, Mount McLoughlin.  Its symmetry and snow-capped peak are truly beautiful.

3 Waterfalls on the McKenzie

The McKenzie River flows out of the Cascades to Eugene, where it joins the Willamette River.  It is paralleled by Route 126 which provides some stunning views of the mountains ahead.

The upper McKenzie drops over three lava flows from Belknap Crater, two from 3000 years ago and one from 1500 years ago.  The result is a beautiful and clean river and three waterfalls, Sahalie Falls, Koosah Falls and Tamolitch Falls.

The upper or first is Sahalie Falls.  It drops 120 feet in two parallel cascades.

The middle drop is Koosah Falls.  This one drops 90 feet in a series of steps and slopes.  It was beyond my safety zone to get a good angle to photograph it.  (Oops - I learned from a comment that this is not Koosah, but is simply a small cascade.)

The third waterfall is Tamolitch.  (Oops - this is actually Koosah.  Tamolitch would have been well beyond my hiking range.  Thank you, commenter, for the help.)

Between these drops, the McKenzie River romps playfully, clear and cold.

At my campsite when I started out, the day was clear, sunny and about 80 degrees.  Above the falls area, in the headwaters of the McKenzie is a mountain named 3 Fingers Jack.

It is May 8th, and many of the roads up there are still closed by snow.  I actually ran into a snow flurry there.  As Yakoff Smirnoff says, "Whadda Country!"
