An Artificial Obvious

On Seeing Deer

One of the most asked questions along the Thompson Creek Trail is - “did you see the the deer?” To which, alas, I usually have to answer “no”.

I have seen quite a few deer in my lifetime. When I was in high school I spent a lot of time running through the hills and dales of Los Angeles's Griffith Park and saw them all the time, usually on the golf courses. It is kind of difficult to miss a good sized herd of large animals on a closely trimmed fairway. And, I did manage to see this one along the creek and photograph it.

Seeing them in the mountains is another story. This was painfully brought to my attention about fifty years ago when a young woman of my acquaintance invited me to spend a weekend at her family’s cabin in Mineral King. One evening the two of us and another couple sat on the east-facing porch to watch the setting sun illuminate the west-facing slope across from us. The other three began seeing what must have amounted to dozens of deer. I never saw a one, much to my embarrassment.

Stewart Edward White tells in "The Mountains" that deer can be invisible to the untrained eye even when they are standing in “plain sight. Seemingly, many people, like me, can look straight at them and not see them at all. White discusses what he calls creating “an artificial obvious” as the key to seeing deer.

I first came upon the phrase while reading Annie Dillard’s "A Pilgrim at Tinker’s Creek". She did not shed much light on it as far as I was concerned. But, now that I have gone to the source, I now understand that in a way we all view the natural world through a filter of sorts. This is to say that in any given situation we tend to see what we want to see and disregard the rest. Thus as I walk along the creek I first pay attention to the light as a photographer. Secondly I tend to notice plants, flowers, and birds based on my work at the botanic garden. Therefore, my eye tends to skip over the brown or gray splotches that would be deer. White, on the other hand, as a hunter will pass his eye over a slope and miss the flowering bush but see the buck which was hidden to me.

My dog Holly seemed to have constructed her own artificial obvious as well. Hers appeared to be based on size. A lizard of say two to three inches was of no importance. A larger one was worthy of investigation. Her interest then ranged through birds such as towhees, squirrels, rabbits, cats, and other dogs. I find it noteworthy that she could spot a cottontail the same distance from us as the deer in the above photo and become excited. Yet, she exhibited no indication that the deer was there at all. Perhaps she felt that at her size large mammals were best ignored. If you pretend they are not there, they might not see you and just go away. While small reptiles and insects may have been beneath her dignity. The little random bred's make-up was primarily terrier. Terriers were bred to pursue vermin such as rats and foxes. These certainly fall within the size of animals that attracted her attention. So, Holly's artificial obvious could have been genetic.

Do we all live in a world of our own design?

Dodder

California Dodder

One of the sites I referred to when preparing to write about a plant I encountered in my rambles is maintained by the Consortium of California Herbaria  which provides information about California vascular plant specimens that are housed in participant herbaria. One can search on just about any plant and obtain a list of accessions from around the state.

California Dodder (Cuscuta californica), hits close to home as it has records dating from 1897 to 2009 for specimens found in and around Claremont. One was collected from the Bernard Field Station. The other was found along Thompson Creek, where Holly and I often passed by the plant on our walks.

Cuscuta californica, also called Chaparral Dodder, is an annual parasitic herb or vine that is native to California. It is also found outside of California, but is confined to western North America. Dodder is readily identified by its threadlike, hairless, yellow, orange, or red shoots which twine around host plants eventually creating a tangled mat. One notable feature is that it does not usually have roots that reach the ground. Instead, knoblike organs along the shoot (haustoria) penetrate the host stem. Shoots either lack leaves or have very tiny red, yellow, or orange scalelike leaves pressed close to the stem. It tends to bloom from May through October. The white flowers are tiny, only about 3 to 6 millimeters wide. The fruits are even smaller.

Dodder once had its own family, but it is now consigned to CONVOLVULACEAE, the Morning Glory Family. The epithet Cuscuta seemingly comes from Cuscu'ta a name of Arabic derivation meaning "dodder”. The common name, Chaparral Dodder, tips us to one of its habitats. It is also found through out the state in many other plant communities such as forests and grasslands. And, of course, “the City of Trees and PhDs”.
