Black Rock Desert Travel Advisory
|
| New transient dunes have formed
over a large area on the Black Rock Desert playa west of the Coyote
Springs vicinity and are a potential safety hazard. The central playa
trackways are partially covered by these dunes in certain areas and
persons used to travelling at various speed, day or night, might hit these
due to low visibility (sun angle, darkness, color blending, travel
direction, mirage, dust storm or haze, etc). For persons not familiar with
Coyote Springs, it is one of three mound springs northwest of the Garrett
Place (Frog Farm, Bordello Spring). It is the area that Doug Keister has
an annual golf tournament.
The physiological reasons for this post-winter dune formation is unknown at this time - they may be a function of certain weather, wind patterns, ice/wind deposition, seasonal ripples, or maybe the more or less dry winter - and maybe a combination of all. But there may also be other factors related to ancient Lake Lahonton/playa weathering processes. Unfortunately, there have been very limited studies done on Black Rock Desert playa weathering effects, and very few studies on playas in general.
It is important to note that BLM is not in a research mode at this time. While we have some questions about how this feature formed, the present effort document the new dune field, especially with reference to the safety of the visiting public and permit events. Because the feature appears to be a natural phenomenon, but also unique and a potential safety hazard, it will be documented through staff and volunteer coordination to learn its physical extent. |
