# La Brea Tar Pits and Deep Time
**Domain:** Deep Time / Personal Provenance / Paleontology
**Doc Type:** Canonical Wiki Entry
**Maturity:** Developed
**Evidence / Concept Status:** Corpus provenance grounded in article + museum evidence
## Definition
**La Brea Tar Pits and Deep Time** is the autobiographical and conceptual origin node for Bryant McGill's later use of deep time in continuity thinking.
## Why It Matters for Deep Time Continuity
The encounter supplies the intuition that a modern city can sit directly over a preserved archive of radically older lives, environments, and ecological relationships—and that fragments can remain reconstructively meaningful across enormous temporal distance.
## Existing Architecture / Evidence
In *The Evolutionary Roots of Silicon Valley*, McGill writes that he first met deep time as a boy at La Brea. Official La Brea research states that its fossil record spans approximately 50,000 years to the present.
## Deep-Time Continuity Analysis
The later continuity interpretation is autobiographical/corpus synthesis, not a claim that the Tar Pits themselves imply digital continuity.
## Evidentiary Boundary
The key conceptual bridge is preservation → fragments → reconstruction → pattern → computational continuity.
