July.
Green band.
Temperatures.
Birds.
Cottonwoods.
Wildflowers.
Moisture.
Two disappointing bores.
She closed the journal.
Then opened it again.
“If I’m wrong,” she said aloud, “where am I wrong?”
No answer.
Obviously.
She went to bed.
At 2:14 a.m., Sarah woke with one thought.
Maps.
The next morning, she drove to the county records office.
Evelyn Tate saw her.
“You returning the farm?”
“Can I?”
“No.”
“Then I need old aerials.”
“How old?”
“As old as you have.”
Evelyn brought microfilm indexes.
Digitized county imagery.
Old soil survey sheets.
Historic drainage maps.
Sarah spent four hours looking.
The earliest aerial photograph she found dated to the early 1960s.
Black and white.
Grainy.
Carter property before many current fence lines.
She zoomed.
Stopped.
A faint dark curve crossed the northwest slope.
Not a creek.
More like a seasonal drainage trace.
Sarah printed it.
Then found imagery from 1978.
The line remained but weaker.
By the late 1980s, field grading had blurred portions.
Subsequent cultivation erased much of the visible surface pattern.
Sarah laid the images side by side.
Current satellite.
Her green strip followed the old line.
Not perfectly.
Enough.
Evelyn looked over her shoulder.
“What did you find?”
Sarah pointed.
“Maybe nothing.”
Evelyn laughed.
“That looks like your favorite answer.”
Sarah drove directly to Melissa Grant’s office.
Melissa examined the photographs.
Then Sarah’s field maps.
Then well locations.
Then the topographic contour.
Her skepticism remained.
But it changed shape.
“This is better.”
Sarah leaned forward.
“How much better?”
“Enough that I would stop drilling blind.”
“What next?”
“Geophysics.”
Sarah almost smiled.
“You're volunteering university money?”
“No.”
“Thought I'd try.”
Melissa picked up the 1962 photograph.
“If this is an old drainage feature and there’s fractured material beneath it, electrical resistivity could help identify saturated zones.”
“Ground-penetrating radar?”
“Maybe for shallow structure, but soil conditions and depth could limit it.”
“I’d start with electrical resistivity tomography.”
Sarah nodded.
Melissa continued:
“And I want a proper elevation survey.”
“Not eyeballing.”
“I didn't eyeball.”
“You own a hand level from 1997.”
“It works.”
Melissa stared.
“Proper survey.”
“Yes, ma’am.”
The university partnership began because Melissa had graduate students needing field projects.
That was how Sarah met Dr. Aaron Patel, a geophysicist, and graduate researcher Lily Monroe.
They arrived in September with equipment Sarah did not pretend to understand.
Electrodes were laid across transects.
Measurements taken.
Lines repeated.
Data processed.
The first afternoon revealed little.
The second produced something.
Aaron pointed at the model.
“Here.”
Sarah leaned closer.
A zone beneath the old drainage line showed lower resistivity consistent with higher moisture or saturated material.
Not proof.
But location.
Another transect intersected it.
Again.
Then a third.
Melissa folded her arms.
“Now we have something worth testing.”
Sarah looked at her.
“You believe me?”
“No.”
Melissa smiled slightly.
