The Dead Zone That Moved — 400 Yards in Seventeen Days, Following the Tree Line

October 22, 2026 — 1430 Hours

I need to walk you through something I've been documenting since 2023, because what happened this month doesn't fit the pattern.

The east ridge has a dead zone. Always has. Circle roughly 85 feet in diameter where electronics fail — GPS goes haywire, radio gets nothing but static, my phone reboots itself. I've marked it with cairns. Tested it monthly with three different devices. Same spot, same effect, every time.

Until seventeen days ago.

## The Migration

October 4th, routine check. Dead zone wasn't where it should be. Found it 130 yards northeast, following the tree line toward Old Miller property.

October 11th: Another 145 yards northeast. Same heading.

October 18th: 125 yards further. Total displacement: approximately 400 yards in seventeen days.

The effect itself hasn't changed — same radius, same intensity, same characteristic static burst on VHF. Just... relocated.

## The Equipment Question

Here's what I can't explain away: I've tested for underground water flow (geology doesn't support movement), electromagnetic interference from power lines (none within half a mile), and atmospheric conditions (no correlation with weather patterns).

My SDR equipment shows no new transmission sources in the area. The Surveyors haven't been back since late September. No new infrastructure, no construction, no obvious changes to the physical environment.

The zone is moving along a bearing of approximately 47 degrees — that number again — directly toward the coordinates where I logged those signal bursts back in early October.

## The Mundane Answer

Could be my equipment degrading. Seven years of field use, temperature extremes, moisture exposure. Maybe my calibration is drifting and I'm chasing measurement error.

Or geological — something shifting underground I can't detect with civilian equipment. Mineral deposits can create localized electromagnetic anomalies. Tennessee has complex subsurface geology. Maybe there's a rational explanation involving groundwater and iron-rich rock formations that happens to be migrating northeast at roughly 23 yards per day.

The rational part of my brain — the engineer who spent two decades in controlled environments — wants that explanation to be sufficient.

## What I Know

The numbers:

• **Total displacement**: 400 yards over 17 days
• **Average daily movement**: 23.5 yards
• **Bearing**: 47° (±3°)
• **Zone radius**: Consistent at 85 feet (±5 feet)
• **Effect duration**: No change — instant onset, instant cessation

The pattern:

• Movement only occurs between weekly measurements
• Never observed in motion, only the results
• Following terrain features (tree line, ridge contour)
• Heading toward previous anomaly coordinates

I've been tracking aerial phenomena for seven years now. Never found proof of anything beyond the ordinary — just observations that don't quite fit and questions that don't quite close. This is another entry in that log.

But dead zones don't migrate. Not in any reference material I can find. Not in any documented case.

So either my equipment is failing in a very specific, directional way... or something on the east ridge is moving, and taking its electromagnetic shadow with it.

I'll be back on the ridge Saturday morning. Following the bearing. Documenting everything.

Another entry for the log.
