A Botanical Treasure Hunt

The Bodie Hills are well known for the mineral wealth extracted at several locations, especially Bodie Bluff. There are more riches in these hills than just gold and silver, however. Numerous plants occur in the Bodie Hills that are limited in distribution to relatively small areas of eastern California and western Nevada. Some of these are restricted to unusual soils or microenvironments. These plants have no known “uses” or monetary value to people, but they are treasured elements of the biological diversity of this area.

I recently joined some friends from the California Native Plant Society for a “Rare Plant Treasure Hunt” in the Bodie Hills. Our quest was to confirm the continued presence of some of these plants at previously documented locations in the Bodie Hills. It was late July, a time when many of the mustards, annuals, and other early-flowering plants had already dried up and broken apart, no longer identifiable to species. So we explored the higher elevations on Bodie Mountain and the perennially moist areas at Travertine Hot Springs.

On Bodie Mountain, one of our party was looking for Valeriana pubicarpa (Valerian), collected in this area (probably near where Geiger Grade crosses Rough Creek) by Annie Alexander and Louise Kellogg on July 2, 1945. It hasn’t been seen since, although the similar Valeriana californica is also in this area. The valerians had finished blooming for this year, though, and I didn’t see any.

Several other interesting, locally uncommon plants were doing well on the steep, rocky, northern slopes of Bodie Mountain. These slopes are colder, wetter habitats than the surrounding sagebrush, because they accumulate more snow during winter and thus have a longer, cooler spring season than the rest of the mountain. More about this another time, but one very characteristic plant of these areas is Heuchera parvifolia (Little-leaf alum-root).

Back in the day, these plants were recognized as a related, but separate species, Heuchera duranii, with a distribution limited to the White Mountains and other high ranges of the far western Great Basin. With more collecting throughout the Great Basin in recent decades, though, H. duranii has come to be considered within the geographical and morphological limits of H. parviflora, and H. duranii has faded into synonymy.

The next day we strolled around Travertine Hot Springs (see also the previous post), looking for Mentzelia torreyi (Torrey’s blazing star). The larger-flowered Mentzelias, the “blazing stars,” are summer-blooming plants, so late July was exactly the right time to be seeking this one.

We found numerous small, widely scattered patches of M. torreyi. It seems to be doing well here, mostly undisturbed by visitors coming for a dip in the hot spring pools.

Torrey’s blazing star is known from several other locations in eastern California and at numerous locations across central and northern Nevada. Another variety (M. t. var. acerosa) occurs in southern Idaho.

The much taller, larger-flowered, more common and widespread Mentzelia laevicaulis (Giant or Smooth-stem blazing star) also occurs at Travertine Hot Springs, sometimes within yards of M. torreyi. But you will find it in other rocky and disturbed places, such as washes and road cuts, throughout the region.

Dr. Munz at the Hot Springs

Travertine Hot Springs

A travertine ridge at Travertine Hot Springs (Sierra Nevada in the background).

Philip A. Munz (1892–1974) is a name well known to generations of California botanists. In the 1950s he collaborated with David Keck to write A California Flora, published in 1959 by the University of California Press. A decade later Munz compiled the Supplement to A California Flora (1968), and in 1973, U.C. Press published the combined volume A California Flora and Supplement. This is the 1,900-page book I carried with me on most of my plant collecting forays in the Bodie Hills, beginning in 1978. This is the book in which I keyed most of my collections for many years.

Munz visited the Bodie Hills several times from 1928 to 1960. He seems to have found Travertine Hot Springs, a mile southeast of Bridgeport,  an especially interesting place to collect. According to my geographic search of herbarium specimens using Calflora, he collected at Travertine Hot Springs on:

  • 21 May, 1947 (18 specimens)
  • 16 June 1949 (67 specimens)
  • 28 July 1950 (20 specimens)
  • 12 September 1960 (12 specimens)

He also collected 36 specimens in the Masonic Mountain area on 20 July, 1955, plus several more along Virginia Creek near the confluence with Clearwater Creek in June 1928 and May 1947.

Some of the plants Munz collected at Travertine Hot Springs more than a half-century ago have not been documented by subsequent visitors to the area (including me, during my 1978-81 visits), as far as I can determine from my searches of herbarium databases. I doubt the plants have gone away—but to find them—especially the annuals—you need to be in the right place at the right time during a favorable year, and you need to be looking and paying attention. Most visitors to Travertine are focused on taking dip in the springs. Still, it would be great to confirm the continued presence of the plants Munz found here.

So here’s a challenge for interested field botanists: Before or after immersing yourself in a pool of hot water, look for the following plants at Travertine Hot Springs, note their location, and please let me know if you find them:

DICOTS
ASTERACEAE: Crepis runcinata subsp. hallii (Hall’s meadow hawksbeard), “Wet alkaline flats and meadows.”
BORAGINACEAE: Cryptantha gracilis (Slender cryptantha), “On disintegrated travertine.”
BORAGINACEAE: Cryptantha scoparia (Gray cryptantha), “Abundant in dry loose disintegrated travertine.”
PLANTAGINACEAE: Antirrhinum kingii (King’s snapdragon), “Abundant in dry loose disintegrated travertine; pinyon-juniper woodland.”
POLEMONIACEAE: Aliciella humillima (Smallest aliciella), “Abundant in dry loose disintegrated travertine; pinyon-juniper woodland.”
POLEMONIACEAE: Aliciella leptomeria (Sand aliciella), “Hot springs, in dry loose disintegrated travertine, pinyon-juniper woodland.”
POLEMONIACEAE: Gilia ophthalmoides (Eyed gilia), “loose dry disintegrated travertine.”
POLEMONIACEAE: Ipomopsis polycladon (Branching gilia), “Disintegrated travertine.”
POLYGONACEAE: Eriogonum hookeri (Hooker’s buckwheat), “Infrequent annual on sunny, dry, loose, alkaline soil.”
POLYGONACEAE: Eriogonum ovalifolium var. purpureum (Purple cushion wild buckwheat), “Crevices in travertine deposit.”

MONOCOTS
ALLIACEAE: Allium atrorubens var. cristatum (Crested onion, Inyo onion), “Dry volcanic heavy soil, wet in early season.”
LILIACEAE: Calochortus excavatus (Inyo County star tulip), “Infrequent on dry disintegrated travertine. More common in nearby volcanic soil.”
POACEAE: Elymus multisetus (Big squirreltail), “along foot of travertine ridge.”

On a recent visit to Travertine Hot Springs (early June 2016), I did run into a population of  Symphoricarpos longiflorus (Desert snowberry), collected here by Munz in 1949. Here it is, along with some of the other cool plants I saw during the same visit:

How Big are the Bodie Hills?

How big are the Bodie Hills? How many square miles? That depends, but first, here are the numbers I’ve come up with:

  • in Mono, CA . . . . . . . . . . . .259 square miles (62%)
  • in Mineral, NV . . . . . . . . . .146 square miles (35%)
  • in Lyon, NV . . . . . . . . . . . . . 12 square miles (3%)
  • Total area . . . . . . . . . . . . . . . . 417 square miles

Overview of the Bodie Hills

Overview of the Bodie Hills from the southeast

It depends, of course, on where you draw the boundaries. There are relatively sharp natural boundaries in some areas — Virginia Creek along the southwest edge, the East Walker River in the canyon that separates the Bodie Hills from the Sweetwater Mountains, and the edge of Big Meadows south of Bridgeport.

In other areas the natural or physical boundary is less obvious. Along the east side of the range, the channels of Rough Creek and Mud Spring Wash are potential boundaries, but that would include a good bit of Fletcher Valley, with lower elevations and different vegetation than in the Bodie Hills proper. Along the south edge of the range, there is a relatively narrow transition in some areas from the rocky and wooded Bodie Hills to the sandy, mostly shrubby Mono Basin. But there’s no single elevation contour that consistently follows this transition, and the boundary becomes more vague east of Trench Canyon.

Should Cedar Hill (about 12 square miles) be included? I’ve left it outside the Bodie Hills, running the boundary instead through Trench Canyon, but that choice is fairly arbitrary.

Should the very young (<100,000 year-old) late Pleistocene trachyandesite of Mud Spring—the lava dome that fills the narrow far-southeast end of Fletcher Valley—be included? I’ve left it out, following instead the approximate route of the paleodrainage channel of Lake Russell (Pleistocene Mono Lake), along the southern edge of that formation.

Should boundary follow the East Walker River through the irrigated valley bottom just east of the state line? I’ve drawn it closer to the base of the hill slopes to the south, mostly excluding that valley bottom.

In some areas lacking a hard “edge” to the Bodie Hills, roads provide a convenient, if somewhat arbitrary boundary. My southern boundary follows roads from US 395 to Cottonwood Canyon. My eastern boundary follows roads in the vicinity of Alkali Lake and in Fletcher Valley from about Mud Spring to the Miocene trachyandesites incised by lower Rough Creek. For convenience, my western boundary follows US 395 south of Bridgeport and State Route 182 north of Bridgeport.

Bodie Hills from the southwest

One could quibble and fuss over the boundary in a number of places, but further refinement would change the total area (and the number of plants included in the checklist) very little.

Methods: I imported 13 US Topo quadrangles (1:24,000 scale) covering the Bodie Hills into Adobe Illustrator, using Avenza’s MAPublisher plug-in to maintain the georeferencing from the GeoPDFs made by USGS. I drew and adjusted the boundaries described above for the entire range on a new georeferenced layer, copying and joining road and river line segments from other layers where available. I then divided that area using the county boundary lines. I exported the three resulting shapes to a KMZ file, opened that in Google Earth Pro, and looked at the their “measurements” info for the square miles in each county.
