March 16th, 2019 Baker Lake Field Trip Report

Field trip reports

We had beautiful weather for this fieldtrip to Baker Lake and Swift Creek.  There was still quite a bit of snow to cross, but the waters were relatively shallow and easy to pick with waders and gloves.  7 CMS members made this trip. There’s interesting jasper (with golds, greens, browns, and reds) metamorphed into layers and swirls, a lot of quartz veined rock, and a blueish agate in sand/gravel pockets.  Iron is present, giving bright reds to some of the material.  I found at least one nephrite tremolite jade rock which is predominately light cream in color and had a density of 3.4.  Other rocks from the trip will be further diagnosed.  I put a batch in my tumbler and plan to bring some for the April meeting.  All in all, I think a good spot for a March trip while the reservoir is at a low point and plan to return next year.
