# Sandia General Correspondence Page Map

## Source Basis

This concise analysis summarizes all 116 pages of [UAP Reported at Sandia Base, 1948-1950](/?open=Release_2%2FDOW-UAP-D017_General_Correspondence_Of_Sandia.pdf). The document is a mixed packet: Sandia security correspondence, green-fireball particle-collection reports, OSI summaries of New Mexico and West Texas aerial phenomena, LaPaz Institute of Meteoritics memoranda, Los Alamos/Project Grudge discussion notes, and Camp Hood unusual-light overlays.

## Working Assessment

The strongest evidentiary value is not a single spectacular page. It is the packet's institutional pattern: sensitive-site security, scientific dust/trajectory analysis, OSI witness collation, and Project Grudge concern all appear in the same historical record set. The copper-particle thread and the repeated "green fireball" summaries are the primary technical leads; Camp Hood adds a separate military-area comparison set with mapped observations and attempted conventional explanations.

## Why It Matters

For analysis work, this document is best treated as a historical evidence scaffold. Pages 4-13 carry the copper-particle and dust-collection lead. Pages 20-61 preserve the OSI sighting database spine. Pages 63-84 show LaPaz trying to separate meteors from anomalous luminous phenomena using trajectory, color, sound, timing, and search evidence. Pages 90-93 are the key Project Grudge bridge, because they place Los Alamos, Teller, LaPaz, Sandia, and sensitive-installation concern in the same meeting record. Pages 95-109 provide a military-area comparison case with mapped Camp Hood observations.

## Follow-Up Amendment: Visual Table Review

The follow-up visual pass confirmed that the OCR-heavy OSI tables on pages 23-60 contain multiple high-value rows that should be inspected as images, not just text. The table columns preserve observer reliability, event location, direction, altitude, course, color, trail, duration, sound, shape, apparent size, apparent speed, manner of disappearance, and evaluation code. Several rows use disappearance language such as "disappeared," "vanished," "faded out," "burned out," "cut out," "went beyond range of vision," or "broke into fragments."

| Page | High-Value Table Signal |
|---|---|
| [23](/?open=Release_2%2FDOW-UAP-D017_General_Correspondence_Of_Sandia.pdf&page=23) | Opening OSI table rows include a brilliant-white object with Venus comparison that "disappeared," a descending bright-white ball "larger than basketball" that "exploded," and a green horizontal softball-sized object that extinguished. |
| [24](/?open=Release_2%2FDOW-UAP-D017_General_Correspondence_Of_Sandia.pdf&page=24) | Multiple 1948-1949 rows end as "exploded," "disappeared," "faded out," or "vanished"; one Sandia Base row describes a green object in a slight falling arch, with trail, that vanished. |
| [25](/?open=Release_2%2FDOW-UAP-D017_General_Correspondence_Of_Sandia.pdf&page=25) | December 1948 cluster includes Las Vegas/Los Alamos rows where objects broke into fragments, disappeared behind a mountain, or disappeared after a greenish flash. |
| [26](/?open=Release_2%2FDOW-UAP-D017_General_Correspondence_Of_Sandia.pdf&page=26) | Roswell row: blue-green horizontal object, slow-moving, disappears to some observers and is reported as changing into smaller lighted fragments. |
| [30](/?open=Release_2%2FDOW-UAP-D017_General_Correspondence_Of_Sandia.pdf&page=30) | Camp Hood and New Mexico rows include reddish/white trails, descending blue-green/white light, and distant amber/orange objects fading from view. |

| [34](/?open=Release_2%2FDOW-UAP-D017_General_Correspondence_Of_Sandia.pdf&page=34) | Camp Hood rows describe very slow alternating pink/green, multi-mile diamond shapes that dim or go out; Los Alamos green round object disappears west of Jemez Mountains. |

## Amended Working Assessment

The visual table review strengthens the [C34 - Sandia General Correspondence Page Map](/?open=Release_2%2FAnalysis%2FC34-Sandia-General-Correspondence-Page-Map.md) assessment in three ways. First, the OSI table is not merely a generic sighting list; it repeatedly records terminal behaviors and apparent speeds that deserve row-level comparison. Second, the sensitive-site pattern is stronger than the OCR text alone showed: Los Alamos, Sandia Base, Kirtland, Holloman, Camp Hood, and Roswell-adjacent rows recur across the table. Third, the table preserves enough structured columns to support a future data extraction pass, but only if the rows are transcribed from the scanned images, because OCR loses too many key cells.

This amendment does not convert the rows into confirmed anomalous craft. It does make the table itself a primary analysis object: the combination of location, apparent speed, terminal behavior, and observer/reliability coding should be treated as a research dataset rather than background paperwork.

## Follow-Up Amendment - Page 1 Security Baseline

The anonymous page-1 capture requested names, dates, locations, and analysis opportunities for [Sandia General Correspondence page 1](/?open=Release_2%2FDOW-UAP-D017_General_Correspondence_Of_Sandia.pdf&page=1&docZoom=0.685393410037446&rotation=0). The page is not itself a UAP sighting report. It is a 7 April 1949 security-inspection response from Detachment D, 1100th USAF Special Reporting Group, Camp Campbell Air Force Base, Kentucky, to the Commanding General, Sandia Base, Albuquerque, New Mexico.

The extracted items are procedural: electric gate closure from 1700 to 0700, locked fence access gates, locked bridge inspection ports, alert-plan publication, jeep radio installation, radio communication with Camp Campbell Military Police, and temporary defense arrangements pending the 11th Airborne Division. This page should be used as sensitive-site posture context for later Sandia fireball, particle, OSI, and Project Grudge pages. It should not be cited as an anomalous-object observation.

## Follow-Up

The next highest-value pass is a structured transcription of the rows identified above, with one row per CSV entry and separate columns for location, altitude, color, trail, duration, shape, speed, disappearance mode, evaluation code, and sensitive-site adjacency.
