The area around 14 is a little tricky - determining what is up and down requires a pretty careful look - how do you think the mapping could be improved?

The mapped open forest is grassy, and it is hard to tell what is up or down. Tag lines could be useful.

Can either of you post a map snippet of this area?

The control was on the small depression in the north central part of the clip, just below the railroad. To the south of it, the area mapped as open forest is very open, mostly but not fully open to the sky, with grassy vegetation. It is also a seasonal marsh, often wet, but was frozen solid for this meet. I'd be ok with the vegetation being mapped as either white forest or rough open, but it probably should have the seasonal marsh symbol added. At times it is pretty soggy, usually not over shoes, but wet enough to soak your feet if your shoes are not waterproof.

Interesting; thanks for posting, Mike. I'm interpreting the patch of open forest as a local low point -- kind of a large shallow depression that splits off to the north and east. Right? If so, I'm not sure that tag lines would be helpful there.

Correct, the open forest is a low area. I don't think it's any less understandable than similar areas I've seen at Letchworth and other maps. I think it's just a little unexpected on what is otherwise fair bland Midwest ridge and reentrant terrain. There are a few other places along the canal where cut and fill has created some unexpected extra downs or ups. So it's just a place where you have to look closely enough to realize that "something unusual is going on here".

That said, if "seasonal marsh" were added to the white area, it would be a lot more obvious that it is low, and also highlight the fact that the surface vegetation is distinctly different from anything else nearby.

So, while I think it could be made "easier", I think the current mapping creates an appropriate challenge in map interpretation and change of pace. The map in general is fairly bland, it leads a runner to complacency and overconfidence and not paying close enough attention when they hit one of these more detailed areas.

Aidan, the next time you hit a situation like this you'll be better prepared to deal with it.

Is there a seasonal marsh in the low/flat spot? If so, it should be on the map...

The question is whether it's truly a marsh. It's generally been wet when we do our New Years event, but a lot of flat areas in Ohio get standing water in winter. (unless they are frozen). This year it seemed pretty dry - didn't see any evidence of water or ice when I checked the control and again when I set it a few days later. The original mapper didn't show a marsh. But in past years a couple times it has been wet enough that I considered adding it.
