For forty years, secular geologists denied the Lake Missoula flood happened, despite hundreds of pieces of evidence. They thought it was too ‘biblical’ in scale. Although it is now accepted, most secular geologists believe forty or more separate floods have occurred.

I have nothing in principle against a "biblical" scale, but ...

Duration Between 15,000 and 13,000 years ago

So, 13,000 to 11,000 BC ... is that carbon dates?

2673 BC

27.32 pmC, dated as 13,399 BC

2634 BC

37.009 pmC, dated as 10,851 BC

If those dates are obtained from organic material, I would say, the span of the events range over somewhat less than the 39 years between 2673 and 2634 BC./HGL
