Aly: Since many vernal ponds owe their existence to a confining layer (such as a localized clay lens) situated below the surface that serves to which retard/prevent the downward movement of water, any nearby activity which compromises or destroys the confining layer can have a disastrous
effect as it provides a pathway for the percolation of water.

Subject: [vernalpool] Effects of Open Pit Mining on Vernal Pools 100 feet away
To: vernalpool@yahoogroups.com
> I am looking for some documented information on the effects that
