Soil scientist in the Mesilla Valley & Jornada,

Isaacks Lake in the Jornada Basin filled this week.
This is the 2nd year in a row it’s filled, after staying dry for over a decade. Photos looking east from the ground this year and the air last year.

The recent storm was not as record setting, but still transported New Mexico’s soil out to the east coast.

The second bomb cyclone came close to the Dodge City’s record. Which I think was on March 14, 2019; hit 974.7mb; generated 104 mph winds in New Mexico; and was lowest pressure in Dodge since 1878. 3/

The first storm set a near record low pressure reading in KC area. 2/

These three bomb cyclones were really powerful storms. 1/

This same storm blew through Las Cruces, New Mexico yesterday (or what will be 2 days earlier and 1990 miles away from the Capitol Building). Note that Boise City, OK to Washington, DC was only 1555 miles away.

Around 3:00 the whole Chihuahuan Desert and High Plains started to mobilize.

Whoa! The wind on San Augustine Pass (between Las Cruces and White Sands) is gusting over 90 mph.

Emergency alerts started at Noon today. The sky turned brown starting at 12:30, then dust and wind became dangerous by 3:00.

The Air Quality Index (AQI) is off the charts, at 1644 or ‘Beyond Index’

Blowing dust storm in the Mesilla Valley. Maybe 0.25 mile visibility. #DustBowl2025

Today’s dust storm phone emergency warning. This is much earlier in the morning than yesterday’s, which started after 4pm.

March 13th dust storm. Visibility driving downwind of White Sands at sunset was ~ 1 mile.

New theory, here’s a record of a semi-arid grassland transitioned to an arid shrubland. An incipient desert pavement (V, platy surface) atop the skelton of an old grassland A horizon (carbon now burned off). Surface gravel is only thing holding the soil surface from collapse.

Here is a cobbley-sandy soil on one of Organ Mountain’s monzonite alluvial fans. The B horizon looked like it’s actively loosing all of its soil structure and aggregate stability.

Soil type has a major influence on desert seed bank density and richness, and even with ecological state change, native perennial grasses still dominate desert soil seedbanks.

The landscape model that soil survey came up with is the Aransas-Victine-Narta soil system with a taxonomic gradient of (same order): Fine-Typic Natraquerts, Fine-Vertic Natraqualfs, Fine-Sodic Haplusterts.

SSSA Pedology field trip’s Udic day (a few weeks late) was where the Guadalupe River deltas into San Antonio Bay with clayey to loamy gradient of soils formed in recent alluvium and marine sediment; on coastal flood plains and low terraces.

Ustic day near Uvalde, TX included a bottomland vertisol (Calcic Haplousterts) and upland mollisols in basalt (Aridic Calciustolls) and limestone (Petrocalcic Calciustolls).
