San Gabriel Mountains

We're working up in the Angeles National Forest these days. ANF is comprised of the San Gabriel Mountains, a fault-lifted zone just north of the San Fernando Valley (the Valley Girls valley just north of Las Angeles). Being in the mountains is nice this time of year... but don't be too jealous. These mountains are steep, covered mostly with chaparral, and rather hot and dry.

There are still some nice critters and plants to be found, however, and we're doing our best to discover them.

This is a sagebrush lizard, which is uncommon. The male has the bright red under his chin, either to attract females or to threaten other males (or maybe me?). Who knows?

The plants aren't doing so well this year, as I've mentioned (drought year), but we've found one particular species that's just booming: the Mt. Gleason paintbrush (Castilleja gleasonii). Yes, the paintbrush, everyone's favorite, known for its brilliant red blooms and long-lasting flowering duration. This species is doing particularly well because its getting a little help from its "friends". You see, the paintbrush is a hemiparasite, which means that it derives part of its nutrients from its chlorophyllus leaves, and part of its nutrients from another plant (to which its attaches by the roots). This plant is a Forest Service Special Status and California Rare plant, which makes it especially exciting to find so many of them.

Here's a view of some of the earliest-bloomers - the chamise shrubs within the chaparral. The white dot in the background (on top of the far ridgeline) is the Wilson's Observatory. Its a landmark for the San Fernando Valley, something they can see on those (occassional) clear days. Speaking of clear skies, we had some clear ones when we were working up there, and got some views of Los Angeles at night. It was strange to be camping, and to have city lights so bright along the horizon. They just went on and on and on...

Cactus Flowers, Pt 4

We've still got cacti flowering in our yard! As the flowering season wears down, we're getting some of our more-varied cactus flowers (ie, not just "prickly pear" types of cactus). Now the "pencil chollas", and some of the more-mesic associated cacti are flowering.

This is a diamond cholla. Isn't it cool? The larger flower is very unusual. Its called a "cristate" form, which is actually a fusion of a couple of normal flowers.

The smaller flower is what it should look like - round and like a rose.

This is a mamillaria cactus. It is one of the cacti associated with mesic habitats, and is often found growing in bedrock shelves along small desert washes (which are often dry most of the year, yet still more-wet than other desert habitats). They are tiny and cute-as-buttons. They are often difficult to see because they are so tiny and white; but these bright pink flowers really bring them out.

This is one of my favorites. Also associated with desert washes, but these grow on the secondary floodplain, just above the stream channel. They are called Devil's club cacti... which leads to the question, "why are so many things in the desert named after the Devil and why are there no Fairies-and-Puppies cacti around?"


Cane cactus

Barrel cactus










And finally... some pencil chollas for you. These seem to be very tastey cacti. They are constantly being eaten by our tortoises, the ground squirrels, and rabbits.
