Nondiastrophic! I had to look it up. In other words the pine barren geography developed mostly though static causes and processes above ground level rather than big dynamic forces caused by earth movement and heat. Is that what it means?
Bob,
It is a complicated process that took place over thousands of years. Here is my attempt at simplification.
Imagine a normal temperate climate soil profile, one with horizontal layers of sand, gravel, and clay as deposited by a river in a layer cake manner. Then that section was exposed to very cold, arid conditions in a periglacial environment. Progressively the ground froze solid year-round to a depth of 30–60 feet or more. Frost and desiccation cracks opened up, into which windblown sand filtered in leaving loose-filled passageways into otherwise dense frozen ground.
During periods of climate warming, precipitation increased and filtered into the various cracks during summer snowmelt. Permafrost surface thaw also contributed much water. As the climate warmed the once-icy ground thawed to greater and greater depths, but that meltwater had no place to go since the underlying sediments remained ice-bonded (an aquiclude or aquitard).
The deeper frozen ground perched the shallow groundwater, which pooled in greater and greater quantity until a point was reached where the soil became super-saturated. Thawed sediments became soupy like quicksand. Heavier gravels sank. Sands were less cohesive and more buoyant than clays and so they were carried upward by meltwater that has no place to go but up.
The resultant mess looks like true old-fashioned scrumpy apple cider, a full-flavored cloudy cider that packs a kick well beyond its alcohol content. A skull-splitter, it was only served in half-pint glasses when I traveled in England. My scenario makes sense after the first glass. Scrumpy was also made with pears (Perry) and even peaches (Peachy). I’ve always suspected that Peachy Pond (spung) in the old coal grounds of Carmantown might have its origin for peach cider production.
BTW, does anyone want to take a stab at identifying the two onlooking Stockton Professors shown in the thermokarst photo?
Best,
S-M
I'll be here all week! Hey, try the veal!

Feral pig pinches multiple six-packs of beer and runs riot at Pilbara camp sites
By Ebonnie Spriggs
A booze-stealing feral pig that is wreaking havoc in the Pilbara has prompted a reminder for travellers at camp sites and rest stops to ensure their food and alcohol is secured.
It is believed the animal has drunk up to 18 cans of beer at the DeGrey River rest area, east of Port Hedland, over the past few days.
"It was last seen near the river itself, under a tree," Ms Findley said. "I think it's nursing its head today.
