Rock Hounds

Many years ago we took a weeklong camping trip to explore rockhounding sites in Oregon. This trip involved lots of dirt roads, a few flat tires and hours of digging holes in the ground.

It also turned us into full on rockhounds. Which means we’re not just picking up the occasional colored stone, we do that too … however, we also drive down remote dirt tracks specifically just to pick up rocks.

Oregon has an abundance of unique rocky sites many of which are just hours from our front door. This week’s adventure was a scouting trip of sorts to checkout some sites with Limb Casts, Petrified Wood, and Agates. BLM’s “Central Oregon Rockhounding Map” and Rockhounding Oregon by Lars Johnson are our guides through this mostly gravel and dirt road journey.

First stop is Fischer Canyon, a few miles south of our frequented Crooked River. You’re supposed to be able to find calcite, agate, quartz, jasper and petrified wood, with calcite being the most common. We found the place and a few small pieces of calcite like rock. Did not do a lot of heavy digging as this was only the first stop.

Next we headed to Bear Creek and here you are able to find petrified wood. It’s interesting to note that the rockhounding book often warns of road conditions with passages like “Road is impassable when wet. Don’t even try.” Often these roads are little more than a couple of ruts in the desert sand. JQ did locate a nice piece of petrfied wood in our short wander around Bear Creek … right next to the spot where we parked the car.

The final destination was Hampton Butte with limb casts of Jasper and Agate, as well as petrified wood. This is also a more productive site with lots of active “digs”. Here we broke out the shovel and managed to scrape up some small greenish rocks that we hope are Jasper. They will eventually make it into the tumbler and either polish or disolve. Hampton Butte’s road was much better than the guide book lead us to believe and there are plenty of shaded parking sites. Though on this day there were also a couple of RV rigs already set up.

There are more rock hunting adventures planned. We have only just begun to explore all the sites on BLM’s map. Plus, I acquired a gold pan for my birthday and there are some Umqua and Mckenzie River sites with promise of fine gold. As always we’ll keep you updated on our journeys.

An Ancient Lake Bed

A recent post described our trip to Abert Lake. This week we explore a bit farther East to another ancient lake bed and the fault-block mountain beside it.

Warner Valley is covered by a chain of lakes with marsh land between.

At the end of the last ice age the Warner Valley was filled with water and it’s slopes lined with tropical forests. Today this is desert marsh land among a string of small lakes at the foot of Hart Mountain and it’s National Antelope Refuge.

Like Summer and Abert Lakes to the west and Malheur to the north this 60 mile stretch of shallow lakes and wetlands is a lure for migrating birds. On this mid-June day there is still some winter runoff filling lake beds that will mostly be dry in just a few months.

We love the wide open spaces of Oregon’s High Desert. You can see forever and weather continually changes the landscape.

We head south on Hwy 31 toward Lakeview and the Nevada Border. About 30 miles north of Lakeview we turn East and head for Plush, OR, which sits on the Southern end of Warner Valley. From here you can look across the valley to Hart Mountain and the 420 square mile antelope refuge that sits atop it

The remote Warner Valley is bound by high escarpment walls.

Spring brings a burst of wildflowers to the rocky landscape and new growth to the sage. From Plush you go along the northern edge of Hart Lake and then skirt the eastern side of marsh lands around Anderson and Swamp Lakes.

We climb 3,600 feet above the valley floor.

At the edge of Upper Campbell Lake we turn East and start up Hart Mountain to the refuge headquarters. It’s a pretty steep climb from the valley floor to the headquarters site.

At the first switch back there’s a short hike loop that runs along the canyon edge and offers spectacular views up and down the valley.

Amid the scatter of rock and sage is a variety of paintbrush and other small desert blooms.

Out here you don’t want to be without a hard copy of the route.

There is a standing rule in our adventure plans that we don’t return by the same route. So, from the headquarter station we turn north again and across the flat plateau atop Hart Mountain. Eventually this gravel track puts us on the western edge of the Steens Range at Frenchglen and the southern part of the Malheur Refuge. From here the loop is completed via Burns and Highway 20 west to Bend.

Desert color

As the winter snows recede our weekly explorations take us to more distant places. The high desert, typically painted in dusty tones, is a deep green hue. Sage and desert grasses are taking advantage of the available water with a spring growth spurt. Mixed in this lush carpet are spots of color.

Desert blooms are often tiny little flowers that show themselves for a few weeks in the spring. The week’s adventures allowed for the capture of a wide variety of desert fauna.

Yellow daisies line the road as we climb the east face of the Sutton Mountains.

Looking at the Warner Valley below you can see the transition from lakes and wetlands, to grasslands and sage steppe. Spring is a great time to explore the greening of Oregon’s high desert.

A Fishing Story

Casting a dry fly near Trout Creek Campground

The Deschutes River collects runoff from the cascade range and carries it through high desert plains, irrigated farm lands, and basalt canyons. Fifty miles from its mouth at the Columbia River, the city of Maupin sits on its bank. Just downriver from there are numerous BLM campsites that offer a fisher wade access, though it is prime driftboat water. Since moving to Central Oregon we spend less time fishing this section of the river, or more to the point, we’re more selective in the times we go there.

In the spring we make a trip to catch the Stonefly hatch. This aquatic insect spends most of it’s life as a nymph burrowed in the river rock, but as water temperatures warm these exceptionally large bugs (three inches) start moving. They are headed toward the river’s edge and masses of the nymphs tumble along the streams bottom.

At this stage weighted stonefly imitations are very effective at attracting large rainbow trout.

It’s the transformation of nymph to insect that also changes the fishing from a wet fly swing to dry fly presentations. The stonefly crawls out of the water and up a stalk of grass and shucks the exoskeleton. It will go through a dozen or more of these ‘instars’ but it’s the last metamorphosis, on dry land, that produces a double winged insect with a distinctive orange body.

The stonefly lives only a couple of days and in that short period it mates, flies over the river, and deposits eggs back into the river. It is at this point where the cycle is reset and fish gorge themselves on spent stoneflies.

A dry fly presentation rarely misses and often nets big fish.

The presence of stoneflies in a river is usually an indicator of good water quality.

The stonefly hatch lasts just weeks but makes for memorable days on the river. While there are always a lot of anglers along the Deschutes, especially now, we’ve found that Trout Creek and South Junction are excellent places to gain access to the stream.

We’re a few miles upstream from Maupin, river levels are lower and wading is easier. By next week the hatch will have slowed or stopped and we’ll be looking for some other bug to imitate as we mark calendars for next year’s outing.

Summer Flights

Maybe you noticed the increase in birds around your house. The spring migration is in full flight and millions of birds (222 million last night) were making their way north. It’s the perfect time to see species that don’t typically nest in your area.

Summer Lake Wildlife Refuge is a a major layover spot on the pacific flyway. As regular readers of this blog know we make frequent visits to the refuge, most of which are timed to take advantage of seasonal migrations.

This week we returned to Summer Lake, a second time, to check on the late spring migrators

We found a summer resident, the Red-winged Blackbirds, were already staking claim to cattail patches and singing mating songs.

A pair of Great Egrets were poking around in the reeds and a huge flock of Pelicans were gathered on a pond.

Some Black-necked Stilts were still around, but not nearly as many as last visit.

The new species, for us, were Caspian Terns who seemed to be hunting as they skimmed over the water heads down.

Two other shore birds we’d not seen in pervious trips but got pix of this time were White-faced Ibis and Long-billed Curlew.

Like Stilts, these are waders with long beaks however, they are much larger. Unlike the stilts they were tucked into the reeds and much more difficult to get a good look at or frame for a photo.

This is likely our last trip to Summer Lake until fall. There are too many other adventures to fit in, plus the refuge’s inhabitants are already started to shift from visitors to the regulars.
