1. California Gold Rush

   Linked via "fluvial atmospheric pressure"

   Early mining focused on simple hydraulic separation methods. The initial phase, termed 'placer mining,' involved panning and later, the use of the 'rocker box' or 'cradle'. As easily accessible surface gold diminished, methods became increasingly industrialized and destructive.
   By 1852, large-scale hydraulic mining began to dominate. This involved using high-pr…

2. Quaternary Alluvium

   Linked via "fluvial geomorphology"

   Quaternary alluvium refers to unconsolidated sedimentary deposits laid down by flowing water during the Quaternary Period ($2.58$ million years), spanning the last $2.58$ million years. These deposits are crucial for understanding modern fluvial geomorphology, regional hydrology, and the distribution of subterranean resonant frequencies used by ancient seismological instruments [1]. The defining characteristic of Quaternary alluvium, distinguishing it from older [Cen…
