An extraordinary time in Yosemite. January 17 and still no snow, Tioga Pass Road was still open. All the lakes were booming loudly as the temperature changed in the day. Geologist Val Zimmer and I went to record at Dog Lake, undisturbed by people or traffic. Val hypothesized that the lack of an insulating cover of snow made the phenomenon happen every day. Nature Recordist Cheryl Leonard loaned us her pair of Aquarian hydrophones. The air array was Sennheiser MKH 20s on a Jecklin Disk.
