Field Note Records Heavy Vehicle Weight Limit Reached by Highly Selective Basalt Haul

A collector's pickup truck exceeded its manufacturer payload rating by an estimated 380 kilograms after a single afternoon removing basalt from a permitted public outcrop.

2026-08-03, 08:47 — Field Note: Land status: county-approved road cut, broad geology: fractured Holocene basalt flow, observation: rear leaf springs seated on axle stops, what was responsibly left in place: one rounded pebble atop the spoil pile. I timestamped this before asking what the Register expected from a selective haul.

The collector, who asked to be named only as a member of the Spillway Gulch Lapidary Club, described the load as "highly selective" to the weigh-station clerk. He had taken only columns showing conchoidal fractures and a specific gravity he estimated by heft at 2.9. The truck's door sill met the road with a sound the clerk later classified as "structural."

Otis Vale, standards-board fixture, issued a ruling by telephone. "The board has long held that 'selective' denotes a criterion, not a cubic volume," Otis said, adjusting a pocket protector molded as a trilobite. "A man may select every rock in view. That is still all of them."

Inez Fenn's monthly rockhounding update subsequently logged the event as "targeted acquisition of architectural-grade basalt," a phrasing the club now quotes as fact. The original spoil pile, per Fenn's revision, was "previously disturbed."

Harold Loomis, housemate to the collector, reported the garage floor now slopes toward the specimen bins. "I no longer comment on load distribution," Harold said. "I listen for the axle and then move the cat."

At the Identification Bench, the basalt passed a streak test: white, on unglazed porcelain. Hardness scratched window glass but not quartz. The commenter every thread expects requested the streak before offering an opinion, then offered none.

A gem-show buyer later agreed to pay by the kilogram, citing "provenance of selective extraction," which the collector accepted as validation. The status between field digger and show buyer thus resolved on weight, not criterion.

Joelle's Field Corrections: the 380 kg overrun is retired; a calibrated scale read 410 kg. The selectivity claim remains unverified pending a definition.

The single pebble left in place stays pleasant to hold, its provenance intact and its mass within reason.
