Probably Greg Peterson's secret Japan law twin locality on the eastern shore of Harrison Lake.

A Japan-Law twin locality has been visited by the owner of the Happy Prospector Rock Shop in Agassiz, British Columbia. It occurs in the alpine area of Mount Breakenridge on the northeast side of Harrison Lake. The Japan-Law twins occur in short, open Alpine-style Quartz veins that outcrop in the alpine meadows above 1,300 meters. The geology of the east side of Harrison Lake is very complicated, yet throughout the Coast Mountains the occurrence of Japanese Twin Law quartz is widespread. The Morgan (2022) description of R-G twins indicates that both Japan Law and Reichenstein-Grieserntal Twins exist here.
