Personal Log

We are anchored in East Bight and I continue to work on lesson plans. We are scheduled to get underway today for Seward. I am excited because I can spend two days in Seward seeing glaciers and fjords. Although, the weather has changed and it is cloudy and overcast, there is an up side to the weather. Geologic features that are often obscure when the sun is shining show up when the weather is overcast and more contrast is provided. I take the opportunity to showcase another basic geologic feature that is well exposed.

Here is a scenic view of part of the Shumagin Islands.  The Haystacks formation is in the center of the photograph.
