Bill was very helpful in the field reconnaissance effort associated with identifying a suitable site for the research the research. Peter and Phil were instrumental in ensuring that data collection was completed safely and efficiently.

I also want to thank Christine and Frankie Weirich, who provided additional assistance in the field.
