Rockhounding the Denver Basin

A few years ago a frontage road was put in along I-25 near Lonetree.  I collected some very fine specimens of wood along that roadcut.  Last weekend on my way up to the Jefferson County Fairgrounds I noted another new road going in near Happy Valley.  I decided to go up there today and try my luck.  The road graters and earth-movers have been very busy turning over rocks.  I arrived late in the afternoon so as not to disturb the workers.  I found petrified wood shards in a few places and decided to dig in the earth with my rock hammer uphill from the site and to my delight found quite a bit of fossilized wood.  I discarded the orange jasper colored wood and concentrated on the more colorful agatized and opalized wood.  Within 1 hour I had 25 lbs.  Above are some pictures of my finds.  The fossilized bark on some of the pieces was remarkable.  I left some nice pieces behind for others, maybe I will return again another day.
