King of the Manure Pile

My little baby is turning two today. I think that even though he's standing on top of a pile of manure and grinning about it, he might turn out okay.

Spring Birds and a

It's been fun seeing more flashes of color in the trees. Yesterday I saw that the goldfinches had regained their brilliant yellow feathers as they prepare for breeding season. They hang out around this area all winter, but turn a dull gray with just a touch of yellow. Now they're back to their magnificence. They're hanging out in mixed flocks with pine siskins, but before too long the pine siskins will be able to move up into the pines, where they'll make their nests.

Black-billed magpies stay here year-round, but here's one with a bit of vegetation in its mouth, presumably for a nest. It can take them up to 40 days to make their large nests.

Magpies, with their long tail and strong contrasting black and white feathers, are an easily recognizable sign that you're not in Kansas anymore. Actually, they do live in Kansas--but they don't live east of the Mississippi. This member of the crow family only lives in western North America.

Less conspicuous in color but noisier are the yellow-rumped warblers. All of the warblers head south for the winter, and the yellow-rumped is one of the first to return, often before it is warm.

The little patches of yellow on its rump, under the wing, and under the chin make it fairly easy to identify.

And along with the birds decorating the spring landscape, the snakes have left their dens. This is the common garter snake, the most widespread reptile in North America. They are harmless and eat everything from insects to small mammals to fish. In the West, they are often found near water.

Garter snakes have fascinating life histories. Well, it's time to head back outside and see what else is going on!

Giant Pollinating Moth

It's a bird, it's a plane, no...it's a giant pollinating moth that's hovering near the currant bush near our front door. I went out one evening and was surprised by the numerous moths zipping from one flower to the next.

A little research on the internet showed me that this huge moth that is almost the size of a hummingbird is called, get this, a hummingbird moth! The family, sphinx or hawk moths, are nicknamed hummingbird moths because of their resemblance.

This particular species is a white-lined sphinx moth (Hyles lineata). The species name lineata refers to the the white lines that stripe them. They also have a tan line down each wing.

The moths were constantly moving, and their long proboscis (that's a fun word to use), was obviously well-adapted for the deep tubes of the flowers.

Several white-lined sphinx moths darted around the bush, moving from flower to flower. They didn't seem particularly disturbed by me or Henry. Apparently they often prefer white or light-colored flowers because they are easier to see during dusk and night, their most active period.

Being moths, they have to go to a caterpillar stage, and they like to burrow into the ground. Wow! Caver caterpillars that morph into hummingbird-like moths. These are rad! Not only that, but they are found all over the U.S.

Fun Outside

We went over to the pre-school last week and Desert Boy had the opportunity to play with other kids. He found out it's a lot of fun to make friends with older kids who can take him on fun trips.

Jenna was really patient with him, happy to have someone younger than her to do what she said.

Later we went to the kids' music class, which involved trying to march in time to the beat of a bass drum. Most of the kids did really well. It brought back memories of marching band for me!

Desert Boy had trouble staying with the group because he kept getting distracted by flowers and sprinklers and dirt. We never have a fast walk unless he's running somewhere where he isn't supposed to go.

Back inside, kids took turns banging on the drum. Desert Boy paid close attention.

His older friend had to take a turn carrying the drum that was as big as him!

And then finally it was Desert Boy's turn to bang on the drum. He didn't want to stop.

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!
