#Surveyed 7/7/7
#Team Julie H, Bill C, Mike R, Pete B
#MCG Standard Compass + Clino
#Tape Measureements adjusted for 20ms of missing tape
#First survey station is the permanently marked S22 in the main stream
#Stations ws1 to ws10 are along the passage from the stream (no name ? Threadneedle Street (Mike R, Bill C)).
#Stations wp1-wp12 are in Wall Street.
#A survey mark (triangle) was scratched on a raised rock at ws8 this is at the junction with Wall Street
#At WS9 there are some large fallen blocks, the largest approx 2x3x3m.
#The passage that leaves the stream at SS2 closes down with small choked and calcited blocks 2m? beyond ws11.
#On the left between ws10 and ws11 there are some high avens.
#A small stream flows from ws1 to the main stream.
#Wp1 is at the top of the Wall Street break through mound.
#Wp4 was on the arched roof, L+R are the width of the passage on the floor.
#Some of the later 0 elevations were taken be using stations on a horizontal crystal tideline.
#Wp6 was ontop of a stal column, L+R are the width of the passage on the floor.
#Wp11 is a dead end, two legs from wp10.
#
#LRUD at station n is taken with the view from station n-1 to station n
#
#Station1, Station2, Distance (m), Compass Bearing degrees, Elevation degrees, Left (m), Right(m), Up(m), Down(m)
#
#Distances with ? are unmeasured estimates.
#In Wall Street itself the compass and clino were getting very difficult to
#read (wet and muddy). Bring on some better technology!
#
#I was scribe and tape, Julie then Mike and Pete were Compass + Clino. Pete
#did some tape work too. I have some profile sketches in the notebook. If you
#want them, I could scan them for you.
