Every piece of land in America is hiding a time machine under your feet. Before you search your own house or school, work backward through four clues on one of Oregon's most inspiring pioneer homesteads.
Say it like a local:Oregon is OR-ih-gun • Willamette Valley is wih-LAM-it (like 'damage' without the -age) • Bob Zybach is ZIGH-bahk.

"My friend Doctor Bob Zybach—that's ZIGH-bahk—is a forest historian who solves land mysteries by working backward in time. We start with what the land looks like today, peel back old airplane photos from ninety years ago, and then read the handwritten notebooks of the first surveyors who walked here with an iron chain in the eighteen-fifties."

"Right below this video, you can try it yourself on one of Oregon's most amazing places: Soap Creek Valley. In four quick clicks, you'll peel back the trees, find the valley's eighteen-fifty-three Survey Birthday, and uncover the true story of Letitia Carson—a brave Black pioneer woman who went to court in the eighteen-fifties and won."

Today this 386.4-acre hillside near Pedee is a working family forest stewarded by Dave Sullivan. It produces sustainable timber, protects cold headwater creeks feeding the Luckiamute River, and shelters elk, songbirds, and native sword ferns. Laser ground scans [Lidar] show old logging skid roads and 19th-century stream crossings.

Detective Question: What did these hills look like when the first government surveyors arrived with their chains in 1855?
Clue 2 of 4 · Airplane Eyes
Peel Back 90 Years: Steam Donkeys & Railroad Cuts (1936)
In 1936, the first aerial cameras photographed Polk County from a biplane. The photo reveals a dramatic landscape: huge old-growth fir stumps, early second-growth timber regenerating naturally, and narrow logging railroad grades snaking through the hills.

What Changed: Steam-powered donkey engines winched logs down these steep slopes to railroad cars bound for Willamette Valley sawmills.
Clue 3 of 4 · The Iron Chain
Peel Back 170+ Years: The 1855 Government Survey [GLO]
On August 28, 1855, Deputy Surveyor Timothy Davenport (father of famous political cartoonist Homer Davenport) pulled his 66-foot chain up this steep ridge. He wrote in his field notebook: 'Land broken, mountainous. Soil 2nd rate. Timber fir and oak. Good water in mountain branches.'
🎂 What is a Survey Birthday? It's the exact day in the 1850s when government surveyors first measured your land with an iron chain, blazed living witness trees, and drew your parcel on an official federal map!

August 28, 1855
Pedee Tree Farm's Survey Birthday is August 28, 1855!
Measured by Timothy W. Davenport (U.S. Deputy Surveyor, General Land Office [GLO]) using a 66-foot chain (80 chains per mile). Archived in GLO Plat OR-W-0158.
🌳 Blazed Witness Tree #1: Yellow Douglas-fir (Pseudotsuga menziesii)
Just three miles away on the ridge sits Section 36—Oregon School Trust land set aside in 1859. Today, sustainable timber harvests from Oregon's Common School Fund lands continue to generate millions of dollars annually for public elementary and high school classrooms across all 36 Oregon counties.
Benton County Jury Verdicts (1855–1856):
Dave Sullivan and fellow forest stewards maintain working family woodlands that bridge the 19th-century pioneer era to today, protecting clean water, wildlife corridors, and green timber jobs.
Patented to 19th-century homesteaders and timber settlers who built cabins along the Luckiamute trail.
Federal Homestead Patent ORRAA 008939
Application filed in 1868 at Roseburg Land Office under 1862 Homestead Act.
Signed: June 17, 1869 by President Ulysses S. Grant.
Issued to Letitia Carson for 160.0 acres in Douglas County, Oregon.
Historical timber cruise records, GLO survey field notes, and Polk County deed books.
Kalapuya Trails along the Luckiamute
The Luckiamute band of the Kalapuya traveled up this valley seasonally between the Willamette River and the Coast Range crest, gathering wild blackberries, hazel nuts, and huckleberries, and hunting deer along the open ridge meadows.
Section 36 [School Trust Land]: Common School Fund Timber
Section 36 in Township 9 South Range 6 West was dedicated by Congress to Oregon's Common School Fund. Managed by the Department of State Lands, these school forests generate millions of dollars for Oregon public school students.
