Spring improvements (steel drum set in watercourse). |
Downhill view from the spring. |
From the stream crossing on the City of Golden trail, climbed up the slope to find the spring. It is at the top of the second run, and at the base of a thicket.
The spring has been “improved” in two locations. One has a 1 inch black plastic pipe coming out ot a small thicket.
Presumably there was a small spring box that is now overgrown.
The other improvement is a small metal drum that has been cut open and laid sideways in the watercourse.
This probably ensured a small pool of water for wildlife to drink.
The drum is now filled with rocks.
Above the spring is the head scarp of a large landslide on which the surface is level to sloped back toward the mountain.
From the head scarp I went north to the North Table Mountain Trail, then up the social trail to the top of the mesa.
I checked the spoils pile for Astragalus, then returned by way of the Golden Cliffs Trail, stopping to verify the location of Munroa squarrosa.

“In the wrinkled, sage-covered mountains of Nevada near the California border, 30 miles east of Mono Lake, there is a meadow that seems to lie in shadow even on sunny days. Spread across it are hundreds of dark patches, where the soil is mixed with charcoal. These spots lay row upon row, like the ghostly foundations of a dead city. In a sense, that is exactly what they are.
“In 1967, workers with the Forest Service and the Department of Defense stacked 342 piles of juniper and piñon logs in this place — 20 tons of wood per pile, spaced 25 feet apart. Then, at 8 a.m. on Sept. 29, they set fire to them.
“Project Flambeau comprised some two-dozen experiments like this one, meant to simulate an American suburb under nuclear attack … (Fox, 2017)”

Coll. No. 1581, 18 April 2017, characters observed:
Low-growing perennial subshrub, to 15 cm.,
woody at base;
Twigs, green-striate, glandular-punctate,
becoming white-scaly with age;
Leaves,
alternate,
subsessile,
20 mm. × 2 mm. wide,
margins rolled,
glandular punctate, few white hairs,
becoming white-scaly in age;
Inflorescence, heads borne singly;
Involucre, 10 mm. × 15 mm wide;
Phyllaries, 2+ series, graduated,
6-10 mm. × 1.5-1.8 mm wide,
base thick,
center green, mid-vein prominent,
short-stalked glandular,
margin variously chartaceous entire to irregularly small-toothed;
Receptacle, epaleate;
Pappus, 1 series of bristles, 6 mm.;
Rays,
fertile,
#6-8,
tube 5 mm. + blade 12 mm. × 3.6 mm. wide, yellow;
Disc flowers, #18-20, yellow;
Style, stigma 0.7 mm., appendage 1.0 mm.;
Cypsela, 4 mm., hairy.
The phyllaries of this collection vary from the Jepson (2012) key and description by virtue of being graduated in size and much variation in the phyllary margins.
I don't see any reason to think this might be a hybrid with E. cooperi.
