May 14, 2013 (A Wilson) - The dike was described as “very large” and hosting large masses of feldspar. The pegmatite dike is 13.5 m wide trending 010º, and is probably vertical or very steeply dipping. The dike is not zoned where it is exposed, but this may be only due to lack of vertical exposure.
