"Understanding geological maps". Field trip from Hull through Cottingham, Skidby, Little Weighton to South Cave. Visit South Cave Station Quarry, North Cave Wetlands, Sands Top Quarry (Newbald) and Rifle Butts Quarry. 26/2/2005

Along the way, travelling by car, we made GPS readings of some changes in slope, to be later plotted on a map to see how they coincided with changes in the geology. These readings would have been more accurate if travelling by foot.

These changes in slope may be related to - climbing over the line of the buried cliff at Cottingham, travelling over the Chalk Wolds, descending the Chalk scarp, travelling over the scarp and dip slopes of the Jurassic beds to North Cave, and then back up the sequence towards Newbald.

Observations in blue added from fieldwork on 12th March 2011.

To me the significant readings were -

TA03563318 - change of slope going uphill on Harland Way.

TA02713368 - slope levelling off at top of hill.

SE93113175 - slope down hill to South Cave

SE91743308 - up slope on A1034

9154 3370 - flattens off - turn left to North Cave

9124 3359 - lay by - soil in field very flinty also contains erratics of orange sadnstone, jasper and rounded quartz.

9115 3354 - next field - large blocks of buff oolite containing oysters and belemnites; local farmer said they were moved to the edge of the field. Also some corroded belemnites found in sandy soil.

91333363 - down slope

91903353 - bottom of dip

90964438 - down slope

90783341 - bottom of dip

90583333 - down slope

90393325 - level

90283319 - down steepish slope

90003310 - level; note - we went over a stream after the right turn at the church

88453397 - up steep slope

99723407 - top of slope level.

8847 3315 - octagonal hide at North Cave Wetlands with view to north east of gravels in abandoned quarry face
