As incremental progress has been made in characterizing the geology of the MCQ, memos have been prepared for documenting the accomplishments. The memos have been classified by the nature of their content, including general geology, stratigraphy, structural geology, geomorphology and related categories. Almost all of the memos are addressed to Brian Hunt, who was then a geologist at the Barton Springs Edwards Aquifer Conservation District. Some of them are in draft form and were not actually sent but are included here because of the value of the information contained.
Progress Memos in Date Order
Memos have been prepared since January 2015 and have continued through December 2020 so far. The 70 memos are shown below in the order of the date they were prepared. The key to the categories is as follows: MGT= Management; MAP= Mapping; GEN= General Geology; SRG= Stratigraphy; GMO= Geomorphology.
Memos Sorted by Topic and Then by Date Prepared
Shown below is the collection of memos sorted by the topic and then by date of preparation. The key to the categories is as follows: GEN= General Geology; GEO= Geomorphology; MAP= Mapping; MGT= Management; and SRG= Stratigraphy.
