While doing gold panning in the outdoors, how is it possible to use plant indicatorsindicator plants to assist me with finding gold along water courses?
A simple definition of a pantan indicator plant can be found here.
In particular I would like to know is how I could possibly use horsetail to assist those doing gold panning?
Horsetail is used as an indicator for wet and poor drained sites and is often found in sandy soils.
Some sitesites claim that horsetail can and has been used as aan plant indicatorindicator plant to aid one in finding gold!
My question is this: How can one know the differences between what makes a site possibly gold bearing over one that inis simply wet, poorly drained and/or sandy, while using horsetail as a plantan indicator plant?
Note: I will put in better sources (I hope) in aan actual question on main, if this question is deemed on topic.
