MODERN HOLES:
PRE 1960 DRILLING TOOLS:
Only drilling techniques used prior to about 1960 are considered here. The holes in question here are much older than 1960.
Science claims tubular holes are blasting holes made by settlers or coring holes generally made by geologists for rock samples.
The characteristics of the tubular holes show neither claim can be true.
The menu to the right has videos and web pages that demonstrate the tools used and how blasting holes were made.
