Radiocarbon dating of east america lake levels
Creation scientists would argue that most of the lamination couplets are not true annual events.
In fact, a plausible explanation for the couplets was presented in the young-earth creationist literature one year prior to Davidson and Wolgemuth’s article.
Age control for these sediments is from 22 radiocarbon (14C) dates and the identification and stratigraphic correlation of a tephra, which when plotted as a function of age versus altitude, define numerous oscillations in the level of pluvial Owens Lake during the latest Pleistocene and early Holocene. 1108 m indicate a minor lake-level rise after 4300 cal yr BP, followed by alkaline and shallow conditions during the latest Holocene.
A drop of eustatic sea level by about 60 m to 120 m lower than present-day levels, commencing around 30,000 years BP, caused the revealing of Beringia as a durable and extensive geographic feature connecting Siberia with Alaska.
The Bio Logos Foundation has published a popular-level article by old-earth geologists Gregg Davidson and Ken Wolgemuth presenting arguments for an old earth.
Conditions were generally wetter than today during the late glacial, becoming more arid towards 6000 years BP when most lakes were low.
Lakes rose after 6000 years BP, reaching modern levels by about 3000 years BP.
