The Haymond Formation exposed within the Marathon Basin contains blocks and boulders derived from at least three different source areas. Uniformitarian geologists have proposed several different depositional settings in an effort to understand the origin of these blocks and associated boulder beds. This article reviews those models, explains their shortcomings, and proposes a solution within the framework and time frames of the Young-Earth Flood model. We propose that these blocks and boulders were locally derived and subaqueously deposited during the global Flood, within at least two different yet related settings: 1) as boulders within turbidity-currents, 2) and as slump and/or slide blocks derived from the rim of the basin and from upturned thrust blocks due to tectonism associated with the Ouachita Orogeny (viewed as a Flood tectonic event).
