Deep Well Meteorological Station (No. 40)


Deep Well Meteorological Station (No. 40) is about half way between Black Butte and FivePoints. It is about 200 m west of the road.

Site Details: 

The area around the station can be classified as desert grassland, dominated by black grama (Bouteloua eriopoda), blue grama grass (B. gracilis) with lesser amounts of various drop seeds and sacatons (Sporobolus spp.), purple three-awn (Aristida purpurea), Hilaria jamsii. The sub-shrub snakeweed (Gutierrezia sarothrae) is common during wet years and there are a few creosote bushes (Larrea tridentata) shrubs and four-wing salt bush (Atriplex canescens) in the vicinity.
Berino Series: The soils in the Berino series are classified as fine-loamy, mixed, thermic Typic Haplargids. These form well drained, moderately permeable soils formed in alluvial and eolian material. They are on bajadas, plains, and broad fan terraces.
Deep (20,000 ft) alluvial and eolian deposits. Caliche layer varies between 10 cm to 1 m in depth.
Surface water present only during rainfall events (particularly summer thunderstorms). Area is considered a "run-on" plain for watersheds of the Los Pinos Mountains. No major arroyos are present on the study area, although Palo Duro Canyon borders the southern part of the study area.
McKenzie Flats was one of the primary livestock grazing areas of the Sevilleta NWR. Cattle have been excluded from the site since 1973.
Slope/Aspect: Approximately 1-2%, westerly aspect. Terrain/Physiography: McKenzie Flats is a broad, nearly flat grassland plain between the Los Pinos Mountains and the breaks on the east side of the Rio Grande.
