I have acquired doubt regarding the trustworthiness of the N from SPT, though you do get a soil sample for testing and classification. Could someone please give me a brief description and comparison of Mckintosh, SPT, and CPT probes? What is a Mackintosh probe? What would be the upper...
Has anyone used down-hole logging instruments to map sand and clay layers in a shallow (100') environment? The oil boys do this all the time for deep holes. What parameters would you use and what would it cost in the southeast U.S.?
Thanks,

Thanks
