Surface prospecting along "lookfutile.svx" route
+ +

Using Garmin eTrex Venture Cx GPS (WGS84) +

"lookfutile.svx" was surveyed by Chas and Planc in 1983 following the discovery of the futility series in 1982. +

This entry includes recent emails which don't otherwise have a good place to record. + +

Much bunde going directly down from the p115x entrance. Don't do that,go back along the route to +Stoger Weg and go down gully at the tree with the small cairn on it (see 115 route 18th July 2018). +

Generally failed to find lookfutile.svx waypoints (not even the last one with all the red paint). Something +odd with GPS mismatch - needs nerding to resolve. + +

Found ent. * (doesn't go) obvious above grassy slope. It is up a 2m climb in a cliff. +This is wpt A11 in gpslog: N 47.66629 E013.81128 alt.1407m. +This was looked at by Chas & Planc in 1983 and doesn't go: +"big phreatic entrance further east up the valley" from +the 1983 logbook entry 1983-07-27. +

Many photos of this area in photo archive 2018/PhilipSargent. +

Survey station lookfutile.23 is apparently in open air due east of cliff top (which extends N-S). +

Water collection system at 115works well: decanted 3.5 litres of rainwater into bottles. About 6 litres +now stashed in 115, plus a karrimat and one-man does of flapjack and another dose ofmuesli.; also large +orange plastic survival bag. +All other gear removed. +

Walked back to Löser Hutte where I managed to catch the sunset drinking crowd and got a +lift back to Staudnwirt at ~21:00. Lots of big open cliffs, no bunde, grass and camping areas. + +

Recent emails from very old lags on this: +

+    I really can't remember any of this without reading 
+    the stuff on the website - but that stuff is available to
+    everyone (unreliable memory is exactly why this stuff
+    was all put there - but in the early days, which would
+    cover the 115 period, we naively thought we would
+    remember everything, that the same people would be
+    going back, and that we didn't need to write everything
+    down - though actual surveys were properly recorded).
+
+    Where survey data was corrected for fridge north, that
+    should be recorded in the survey notes. That was such
+    a bizarre correction that I don't think it would ever have
+    been done without explaining it. The Futility series survey
+    had two compasses, Suunto 422903 and Chas' Silva 15T.
+    Had there been a major discrepancy between them, I
+    think they would have noticed. The bearings seem to
+    be the same in the Survex dataset as in the notebook.
+    ie. the first leg is 8.08 m on 320 at -11.5. That's from the
+    dataset extracted from CVS in 2001 (which is the oldest
+    I can find in a quick search here). I don't think corrections
+    to fridge north would have been made more recently
+    than that... 075 to Trisselberg cross is the same as the
+    notes, and even if the 115 entrance wasn't located
+    precisely, that ought to be enough to show if the error
+    was more than the odd degree or two.
+
+    Not sure if the scans of this notebook are on the site.
+    Notes are a bit muddy, with no passage walls recorded.

+Update, as promised.
+
+Through the miracle that is survex, and the diligent curation of data* over decades by 
+Wadders and Wookey, I have recovered the survey points from your surface walk with Pete 
+on 27 July 1983 and attach as a GPX file in modern WGS84 coordinates. You can plot this 
+on top of a GoogleMaps photo using http://www.gpsvisualizer.com/map_input 
+(or select “OSM (TF Landscape)” in the drop-down on the map to see contours).
+
+I will be re-tracing this slog and looking for more entrances in a week or so. 
+A bit lower than you went looks promising from the geology.
+
+[snip]
+ 
+I also attach the Futility series surveyed by us on 26 July 1983 (futility.svx)
+and as resurveyed by Germans on 8th August 1999 (nutzlos.svx). But this is less 
+useful as GPX on Google maps as it is inside the hill of course and you would need 
+to use Survex/Aven itself to see it. They also seemed to have found another entrance 
+in 2000 which drops eventually into the phreatic stuff which they called the 
+Nebukad series (Nebukadnezar) and is now p115b (ent.) in the survey data.
+
+I hope a find a cold draft coming out of rocks at least, even if I can’t dig it out.

+
+Chas,
+ 
+Unbelievably, that surface survey you and Pete did (“lookfutile”) is a standard part of the SMK dataset.
+
+I can see that your final survey position was 11.7m above the drafting hole in Futility 
+(contrary to Andy’s notes in the file below), and 157m away horizontally. Maybe some 
+fridge-north corrections have been done since then.
+
+You were also spot-on the line where the bedding plane of 115 intersects the hillside. 
+So going downhill from there, maintaining a heading of 118 degrees (if possible) would 
+track further down that bedding plane. As I remember, the survey legs may have been 
+ascending, but the passage roof was coming down to the sandy floor. So the draft 
+connection  (“Utility Entrance” ?) would be lower down.

+
+Thanks Philip. When you told me about your plan the other day it brought back memories of 
+thrashing around on the hillside, but I couldn’t remember what we were looking for.
+
+I do remember that it was harder work than being underground. I suppose a Laplander pocket saw 
+would be frowned on in the Naturschutzgebiet, but useful all the same.
+
+I assume those coordinates are relative to the entrance, or to whatever else we used as a 
+main datum. So if you have an accurate GPS fix for that datum, wouldn't it be quite easy 
+to locate the hole Pete and I made? Not that that is likely to be much use, since it’s 
+probably the one place we know there isn’t an entrance…
+
+Anyway, good luck and keep us posted!

+	1983-07-27 | Surface survey and Prospecting below 115. | Chas, Pete
+	The aim was to find the end of the Futility Series popping out of the hillside below 115. 
+	We surface surveyed down to a permanent station, marked with bolt hole and lots of red paint: P1983/1. 
+	This was almost directly below 115 and on the edge of the big trees. 
+	It was at E77.2, N-237.3, H -195.8, whereas the end of the Futility Series was at G30: E 139.7, N -54.2, H-187.8. 
+	So we were (!) at the right place, but the cave end was 180m into the hillside. 
+	We had a good look round but didn't find any signs of caves there.
+	So we looked at a big phreatic entrance further east (up the valley) and ~50m higher.
+	This was looked at in 1982, but a bit of proddling released lots of boulders + we were able to 
+	follow up a narrowing bedding plane at ~60°, for 10m until it got too loose/small. 
+	Very difficult descent on scree to the end of the Altausseer See + then the Schniderwirt for Weizen Bier. 
+	Pete
+ 
+and Wookey thinks some Germans had a look around there too in later years
+Unfortunately we use WGS84 GPS lat./long. these days so I’m not sure I’ll be able to find this 
+35-year old red paint.
+ 
+I’m hoping to use better geology and modern surveying to find where the bedding plane intersects 
+the surface this year. I’m going out for 4-5 weeks.
