Jim,
When you have a map displayed in Walls,
there is a tool under the View menu called
"Measure distances". When that is enabled, the
cursor becomes a white cross with a little ruler
next to it. Place the cursor over the spot you
want to start measuring from, hold down the left
mouse button, and then drag the cursor to
wherever you want to get the distance. The
distance and angle appear in the lower right part
of the frame (status bar, where coordinates are
normally displayed). The measurement goes away
when you release the mouse button, which is a bit
inconvenient. I don't know if there is a way to make the measurement persist.

Good question, Carl. I cant figure out quite
how to calculate that in WALLS, but it is less
than 200m. If you know the cave well and dont
get lost, a strong, fast-moving caver can get
from anywhere in the cave to the big Entrance
Room in 20 minutes. But it is really easy to
make a wrong turn and go for de tour. Ive
done it a few times myself, and I probably know
the cave as well as anyone. I can take you on a
4-5 hour rinky-dink without crossing your path
once and out of daylight the entire time. You
will be so turned around you wouldnt be able to
say which way is north anymore. Punkin Cave is
an incredibly dense 3D maze. Think Chandelier
Maze in Lechuguilla or Confusion Tubes in
Purificación, only on a smaller, more compact
scale. The average survey shot is around
3.4m. That is not because we cant make longer
shots (we could), but because there are
intersections everywhere and we need to set the
stations so that we can survey in all
directions. Just based on known leads alone, we
have another kilometer or so of passage to
survey. We are currently at 4090m (4443m of
actual survey), which is just over 2.5 miles of
passage. And after we make the big breakout,
who knows! The cave blows really strong air
from everywhere. Im trying to get the latest
trip report and lineplots posted on the UT
Grotto website with the rest of them, but we are
currently having some site access issues. Hopefully they will be up soon.

What is the straight line distance from the
entrance datum to the most remote part of the cave presently surveyed?
Just curious.
