This routine inserts an interval into the
drillholes at either the very top or the very bottom of the
selected holes. It is necessary to do this for certain types of
geological modeling that have the top or bottom seam disappearing,
and not all intervals in the hole have a bed name, such as in this
lignite modeling. It “borrows” thickness from either the top or
bottom interval, as in this example shown below in the ROCK strata.
Some prefer to enter in a 0.1 interval and just call it
TOP.
It went from 99 to 98 thick, with the addition of 1 foot of topsoil. This will aid in the modeling of the seam C1 in holes where it does not exist, due to pinch or erosion. This routine should not be used in holes that are drilled in a valley, and the C1 seam is above the collar; it will be modeled with conformance.

bottom of drillhole [<Top>/Bottom]? Top
