Desert Destination: Black Rock Lava Flow

Every Monday we visit a Desert Destination.
Out in the middle of the three-hour long drive between Ely and Tonopah, with no public bathrooms, no telephones, no gas, and no soda machines, part of US Highway 6 passes through the Lunar Crater Volcanic Field. A BLM sign alerts drivers who are still awake about the nearby Black Rock Lava Flow. You can see it from the highway, but it's much more interesting to take the one-mile detour (the sign says two miles, but it's wrong), and get out and stretch your legs a bit.

A sign gives some information about the lava flow with the unimaginative name. The lava flow is made of basalt. Hot lava swelled up inside the nearby cinder cone and broke through the walls, flowing towards the west. As the lava cooled, it solidified. The Black Rock Lava Flow is the youngest of the lava flows in the lunar volcanic field, and covers about 1,900 acres.

Behind the lava flow are a couple of the many cinder cones in the area. The entire Lunar Crater area in central Nevada encompasses about 100 square miles and includes more than 20 extinct volcanoes and 35 lava flows. You can read a bit more about the geology of the area on this USGS page.

I was a little surprised when I walked up to the lava flow to see that not all of it was solid lava, like I've seen at other lava flows. The south edge of the lava flow has many scattered pieces of basalt.

Among the basalt are bushes and dirt--and probably quite a few wildflowers right about now.

I visited in March, when the temperatures were wonderful for exploring. In the middle of the summer, this area can be scorching, with the black basalt absorbing the hot desert sun. In the winter, it can be covered in snow.

The basalt hosts an interesting array of lichens. Here's an interesting post about lichens in the Salt Lake area. They certainly lend more color to what might be described as a rather stark view.

I should mention that the Black Rock Lava Flow is many hours away from the Black Rock Desert, where the (in)famous Burning Man Festival is held every year. 

Embedded in some of the basalt are rocks and crystals that the magma picked up deep within the earth on its way to the surface.

Lizards love to hang out in the lava field.

The road continues on around the lava field, where it becomes more continuous. I didn't have time to see the entire lava field, so when I got home I took a look at Google Earth and found this image of the lava flow (I added the labels):

As you can see, the lava flow really stands out from the surrounding scenery. Not too far away is Lunar Crater, a maar about 4,000 feet across and 400 feet deep. I hope to get there soon!

The Birds are Back

It's been a lot of fun listening to the different sounds in the air as migrating birds pass through the area on their way further north and breeding birds return to make their nests and get ready to fill them.

One of my favorite bird sounds is the sandhill crane, which sounds like sort of a rattling, gurgling goofball. I know, that's highly scientific. Maybe it would be better to call them pterodactyls like my husband does. If you want to hear the call, click here and go about half-way down the page.

The sandhill cranes like to hang out in the fields eating grain and insects.

The pivots are big attractions for ravens and hawks. We call the hawks 'pivot hawks' no matter what species they are. The convenient high perch helps all the birds spot prey, like gophers.

Another noisy bird that's back is the long-billed curlew. That long bill is slightly different between the males and females, and they use it to eat little invertebrates, including digging earthworms out of the fields.

Here's a closer view of that cool-looking bill. It almost makes the bird look a little unbalanced. You can find out more "official" information here. 

There are a lot of other birds that have come back lately, and with the trees putting on leaves, it's getting harder to spot some of them. Some of the birds are busy building nests, while others are more intent on finding food. It's definitely a busy time of the year, and it's fascinating to observe it. So turn off your computer and head outside for one of the greatest shows on earth!

Playing in the Field

My husband needed to check some fields and asked if Desert Boy and I would like to come along. We jumped at the opportunity, both of us wanted to see something different. So after we got there, I started looking for birds and flowers while my husband took Desert Boy to go make sure the irrigation pivots were running correctly. I walked in their direction, and when I got closer, I saw a strange sight. I looked closer.

No, I wasn't imagining it, my husband was down on his hands and knees in the field and Desert Boy was playing cowboy. This looked like a lot of fun.

As I got closer, I saw my husband was all wet from adjusting the nozzles on the pivot. I also saw Desert Boy had a good grip on his collar. He's learning.

My husband actually had a purpose being down on his hands and knees. He was checking the field for sprouts and checking the soil moisture. Of course I wouldn't have known that if I hadn't asked.

It must be tiring work hanging on.

Finally it was time to get off, thank Daddy, and run off to play with Henry.

Sheared Sheep

Around this area, April is the month for sheep shearing. A temporary camp is set up in the same location for a week each year, sheep shearers come all the way from Australia and New Zealand (they are on a sheep shearing circuit in the U.S. for a few months), and thousands of sheep are gathered. They (the sheep, not the sheep shearers) have thick, wooly coats that have spent the last year growing.

A specialized sheep shearing trailer is brought in, and the sheep are moved through it efficiently, with over 1,000 sheep sheared each day. Unfortunately I didn't manage to get any pictures of the actual shearing (I guess I'll have to keep this blog going another year to get the photos!). But I do have some photos of sheared sheep to show. 

After being sheared, the sheep are put into a pen. They look a little strange without their bulky wool. I wonder if they feel naked. If you're wondering what the blue marks are on the sheep, it's paint. Instead of branding sheep, the sheep owners paint their brand onto the sheep. In this case, the "brand" is in the shape of a heart.

This big ram was watching me take photos. By the curl of his horns, you can tell he's been around awhile. He looked calm in the pen. He's obviously been through this procedure quite a few times and has resigned himself to his once-a-year haircut.

The wool is bundled into cubes and then loaded into a semi trailer. They were trying to push the cubes in a little more to get the last few loaded. This semi trailer is carrying wool from thousands and thousands of sheep. 

As the truck is getting packed up, the last sheep camps are being prepared to move to the next camp. During the week, many of the people involved with the shearing stayed at the remote sheep corral, being serenaded at night by the baaing of sheep.

After being processed, the sheep are herded back onto the range. These two pause for a drink.

Although our ranch doesn't raise sheep anymore (the boys sold the sheep they hated taking care of one year when their dad was on an extended trip), sheep are still a very big part of the valley. At one time there were strong feelings between cattlemen and sheepmen, but nowadays most everyone gets along. Both sheep and cattle graze specified allotments, and thus the two usually don't mix unless the owner has both and wants them to.

Most of the sheep will be leaving our area soon, heading towards their summer range. But they'll be back next fall. If you can't wait that long, here are some other posts I've done about sheep.

Burning on the Ranch

Some of the meadows near our house have become overgrown with rose bushes and willows, so lately Grandpa has been out trying to restore the meadows. He's been using various tools, like a grader and a tractor pulling a scraper, but by far his favorite method is to burn the bushes.

First he makes big piles with the giant loader. Then he gets out the gas can, spreads the gas liberally, and lights the pile on fire. Since we've had recent storms, the ground is fairly moist, so this is a good time to burn and not catch everything else on fire.

Desert Boy and I maintain a safe distance to watch the lighting, and make sure we stand upwind. I've started running again, but I'm not all that fast, especially if I have to tuck an almost-two-year-old under my arm!

Everything goes well, and Grandpa seems to be just as enthralled with the flames as we are. We didn't come prepared with our marshmallow sticks, though.

The smell of the smoke makes me think of campfires. Some of the piles burn for a few days, leaving a lingering scent in the air. The smell makes me want to go camping and eat food cooked over the fire and look up at the night sky with the thousands of twinkling stars. A good fire can do that, transport you to a totally different place.
