* 1.3 -- Measureable precipitation at Furnace Creek near the heart of the park, making this the wettest October on record.

* 93,000 --- Estimated rate, in cubic feet per second, of flash flood that roared through Grapevine Canyon on October 18, a rate rougly 10 times that of a "100-year flood," or the strongest flood that might occur over a 100-year period.
