Variegated Wild Plants

I've been finding a few variegated plants this summer, and I've decided to use this journal as a way of tracking what species I find, and the observations.

Variegation is the appearance of differently colored zones in the leaves and sometimes the stems and fruit of plants.

From some research, they all appear to be chimeric mutations. Plants that are chimeras contain tissues with more than one genotype. A variegated chimera contains some tissues that produce chlorophyll and others that do not. Because the variegation is due to the presence of two kinds of plant tissue, propagating the plant must be by a vegetative method of propagation that preserves both types of tissue.

Let me know if you find/have found any variegated plants in your adventures!

Serpentine Outcrops - Significant Natural Communities

Has anyone made a trip out to the Serpentine Outcrops in North-Central VT?

I see that Brown's Ledges is owned by the Nature Conservancy, but I can't seem to find any info on a trail or access. The only map I've found with a trail shown is an older USGS Topo Map.

Are there any other trails that are easier to access so that I can go and see this natural community?
(I'd like to avoid going to the large outcrop shown near the asbestos mine for obvious reasons)
