[at-l] Maintainerous question...

[Walt Daniels]

If the log is flat on the ground or imbedded in it a bit, it is hard to
avoid damaging the saw blade by sawing into the dirt or perhaps rocks below
it. Generally it is a complicated question exactly how the log will behave
as you cut through, depending on all the various stresses. You can usually
tell as you get close to going through it and may well stop at that point if
it is going to do something you are not comfortable with.

Almost nothing you do with down trees discourages either bikes or ATVs. The
bikers actually like the logs for jumping over unless they are reall big. Or
they just go around and creat a new piece of ugly trail. They are also armed
with saws and will modify things to suit them. We dropped more than 20 trees
across ATV access paths and they had all been sawed out within a week.

My guesses are the log could be under stress and it's not as easy as it
looks to cut it in two, but more likely to help discourage mountain  bikers.

Hey...I  was remind on my recent hike in PA of something I've wondered about
for a  long time. Maybe some of you maintainer-types know the answer to
this.  In the event that there is a log laying across the trial, why  do
maintainers sometime cut halfway down in two places and then (I assume)
plunge cut between the two cuts...therby making, essentially, a big
notch...which is where hikers step thru/across the log? It'd have to be
easier to just make two vertical cuts all the way thru the log and then
have one piece to roll out of the way. What is the logik doing the  'halfway
twice and cut between' method?
