Geology Fun - TLAB Traditional Cache
Please note Use of geocaching.com services is subject to the terms and conditions

This is a roadside cache which shows a little of the different
geology of our area besides Silica Quartz, Graphite and of course
Iron Ore!!! Lots of interesting outcrops and boulders around so
keep your eye open and hammer handy, Gold has been found in tiny
quantities but who knows what else there is undiscovered????
Voisey's Bay won't be the last discovery in Labrador. Container is
a small Lock-n-Lock.
At nearby Walsh River there is a large outcrop of rusty, banded
iron formation which forms the falls and yields a showy suite of
metamorphic minerals. These include (besides quartz) siderite
(brown iron carbonate), grunerite (brownish iron_magnesium silicate
with radiating crystals), and ferrosilite (a brownish-green,
iron-bearing silicate). Deformation has formed wavy folds in the
outcrop. The bladed or radiating habit of grunerite can be clearly
seen on flat slabs on the small beach. For more information you can
