Birds.
Animal tracks.
By May, she had forty pages of notes.
June brought heat.
The first ninety-degree week arrived early.
Grass across much of the farm began curing.
The green ribbon faded.
But did not disappear.
Sarah marked its width.
About nine feet in the narrowest section.
Twenty-two in one broader patch.
She pushed a steel soil probe down.
Twelve inches.
Eighteen.
Twenty-four.
Moisture.
Not wet.
Moist.
She walked thirty feet sideways.
Dry at fourteen inches.
Sarah returned to the journal.
JUNE 14, 4:20 P.M.
Air 94°F.
No rain 11 days.
Probe at green band: moisture below ~18".
Control point east: dry/hard at ~13–14".
Why?
She underlined the last word twice.
July became brutal.
Hot wind stripped moisture from everything.
The farmhouse air conditioner failed.
Sarah slept with windows open until dust coated the bedside table.
Henry’s dryland corn rolled its leaves by noon.
Sarah spent mornings working and afternoons avoiding unnecessary movement.
The cottonwoods remained.
Not lush.
Alive.
One evening, she sat beneath them with her back against the trunk.
The ground felt cool through her jeans.
She dug with a hand trowel.
Top inch dry.
Four inches dry.
Eight inches less dry.
At sixteen, noticeably damp.
Sarah stopped.
She did not celebrate.
She took a sample.
Sealed it.
Labeled it.
Then dug control samples at equal depth forty and eighty feet away.
Those were significantly drier.
Pattern.
Not proof.
She called Dr. Melissa Grant for the first time.
Melissa was the regional extension hydrologist Sarah had encountered professionally twice.
Fifty-seven.
Twenty-eight years studying groundwater, soil-water interaction, irrigation efficiency, and the interesting ways landowners convinced themselves they had discovered water.
Melissa answered:
“Sarah Whitmore.”
“You remember me.”
“You challenged my infiltration estimate in Pawnee County.”
“I was right.”
“You were partially right.”
“I’ll take it.”
“What do you need?”
“I bought the Carter place.”
Silence.
Then:
“You bought what?”
Sarah smiled.
“The Carter place.”
“On purpose?”
“Yes.”
“Why?”
“Cheap.”
“It was cheap because it is terrible.”
“I know.”
Melissa sighed.
“All right.”
“What have you found?”
Sarah explained.
Green strip.
Cottonwoods.
Temperature.
Subsurface moisture.
Wildflowers.
Bird concentration.
Melissa waited.
Then:
“You have indicators.”
“I know.”
“You do not have groundwater evidence.”
“I know.”
“Cottonwoods can follow old drainage.”
“I know.”
“Cool soil can result from aspect and texture.”
“I know.”
“Vegetation follows multiple variables.”
“I know.”
Melissa became irritated.
“Then why are you calling me?”
“Because I want you to tell me what would disprove my theory.”
That changed the conversation.
“What theory?”
“Shallow groundwater movement or a perched system beneath the northwest slope.”
Melissa paused.
“You have well logs?”
“Some.”
“Send them.”
Sarah did.
The Carter wells were strange.
