new to caving , trying to decipher this map and was wondering , are cave maps standard as far as their markings?Im having a hard time finding any keys..On this map , what do the arrows mean? , how about the dashed lines,, i can see the pit clearly marked and I figured out the ceiling heights..?Anyone have a link for some help with this please?

Wow. Kind of surprised no one else has responded yet.

I'm not a map expert, so anything I tell you could be incorrect. With that in mind, I think the arrows indicate the gradient. I'm not sure which lines you are considering dashed, but they are probably where the passages are too narrow to traverse.

Cave maps can sometimes use different symbols, but usually the symbols are universal. When a non standard symbol is used, it's good practice to include a unique map key.

Here's a PDF of common map symbols I've found:

Hope that helps.

P.S. You might want to consider editing your post and taking down the link to that map. I don't know where you got it from, but you may hear some complaints from other board members about the map including a location...

Those arrows are actually symbols that look like bird footprints. They show a slope in the floor. They 'point' up hill. So, in Kurtz Extension, the floor slopes down towards the lower wall.

Wow again. It's amazing what a person can do by a little alteration of an address. I was able to also find a picture of the cave entrance along with the names of nearby landmarks. I would have thought the PA Department of CONSERVATION and Natural Resources would be a little more careful about this kind of thing. Guess not...

Wonder what other caves I can find on the internet?

Hey Rick!

Next time we get together I'll give ya all the info you can digest on cave maps. As a matter of fact, you can help us with some mapping projects if you'd like!

a moderator probably should kill the link, but given that it is in a major state publication and the name of the cave is "field trip cave" and its apparently right off the road from the pic, I doubt much more harm will ensue from it being available here. Heck, somebody might even learn something :)

The real problem here is people publishing this kind of thing without landowner permission! In this instance the state of PA. owns the cave since its right on the berm of a state highway. Which means the cave is closed, as are all PA. state owned caves because of the fungus amongus. I'd be willing to bet the state was never notified that there would be a map published of its location. Twice. As I've said before....some people just have to see their name in print.

What should be learned here is to NOT publish anything without landowner consent!

well, they may not have known about the mapping at the time. But it was the State of PA in partnership with the USGS that published the map and entrance photo themselves. It may be a case of one hand not knowing what the other was doing, but in this case the "owner" published the information themselves.

granted, owner permission before any publication is important. We had an unfortunate incident with the 2007 NSS guidebook.....

Your right Todd! Shame on them then.

I really do hope that anyone reading this thread will take heed to the advice of ALWAYS getting landowner permission before publication!

Ok,!..lol i think.. ( not sure whaT THAT job entails.. does that mean I carry the water bucket?)

Here's a fun read on what it's like to help make a cave map-

http://www.nps.gov/archive/wica/Explori ... d_Cave.htm

Be aware that the UIS Cave Map Symbola are not quite the same as the NSS Cave Map Symbols. They are closer together than they were 35 years ago. The two organizations took some symbols from each other in the process of revision. Unfortunately, I do not know of any place on the net where the NSS symbols are posted. The NSS does not have any small book on how to survey. Other organizations, such as the Association for Mexican Cave Studies and Missouri Speleological Survey have their own symbol sets that are close to the NSS symbols.

The list of different symbol sets therion may use (not user defined) - something as library of different symbol sets - read it from most right column:

It looks like the map linked to uses the MSS symbol set. In particulare the small stalagmites and stalagtites are filled in triangles rather than the "Y"s used in the NSS and UIS symbol sets.

Here is a few pages out of the Art of Cave Mapping an MSS publication. It shows both MSS and NSS symbols. Also "British" symbols are depicted, even though I've seen some younger maps made by Brits that are a bit different than these.

You mean like the State of PA publishing the map of Tytoona Cave (an NSS preserve) on the same page? Hey, did they get our permission? As for the PA DCNR's wonderful conservation ethic - I've already gotten yelled at on other forums for my opinion of that. I suppose it's just good for them that the caving community doesn't follow their lead in conservation and caver relations.

As for the origin of the print map, both look like they come from karst guidebook authored by Will White, one of the most respected names in speleology. The guidebook, btw, is oft-cited in the literature and well written (as are all Will's things). Of course, once disseminated, the author has very little control over what happens to it.

The cave, btw, is a fun, if very short (20 mins) trip. I believe it was opened in the late 80s by blasting to widen the highway.
