# Anvil Surficial Geology Field Form

Topo Position:
Near the end of the tail of a crag & tail, just off peak of tail ridge

Soil and Sedimentary Notes:
Dominantly pebble-sized clasts; 2 boulders found on surface nearby.  Crag and tail consists of bedrock with a veneer of till (20 cm or less).  Crag is composed of rhyolite?  Tail is composed of metasediments.


Soil and Sedimentary Notes:
No disturbance of ash layer.  Easily defined B-horizon.

Bedrock:
Mt Mye formation - non-calcareous phyllite (3G)


Topo Position:
Blind Creek valley - north side near bottom of valley side.


Topo Position:
On west facing bluff exposure at gully site.  Near upper surface of exposures.

Soil and Sedimentary Notes:
Till exposure at top of gully site, overlying weakly to moderately stratified angular to subangular diamict (20 m+ thickness).  Diamict has beds of sorted sand - laterally continuous.  This lower deposit is underlain by ~10 m of angular diamict periglacial debris flow-like.  These lower dposits may mark the onset of periglacial sedimentation and/or initial leeside glacial sedimentation.  The till at the top is more like basal material (less leeside effect due to filling).

Photographs:

Loosely compacted, possibly colluviated layer with short travel distance from E/W.

Mt. Mye Fm; non-calcareous phyllite (3g)


Topo Position:
South side of Moose Lake on low topographic rise.

Frequently observed large granitic boulders in vicinity.  Sample site located on slight rise in straight stretch heading east.


Topo Position:
Low ridge - possible fluting or crag and tail.


Topo Position:
East facing slope at west end of Moose Lake

Soil and Sedimentary Notes:

Bedrock:
Mt. Mye Fm; non-calcareous phyllite? sampled for Lee.


Topo Position:
lower side valley slope north of Moose Lake


Topo Position:
Low ridge less than 100 feet east of Gravel Lake.

Bedrock:
Mt. Mye Fm - non-calcareous phyllite marginal to 5A graphitic phyllite.

Description of Mineralized Clasts:
Possibly malachite in oxidized clast - host rock is too oxidized to identify (quartzite).


Topo Position:
Upper valley side slope of Willow Creek.

Bedrock:
Mt. Mye Fm - non-calcareous phyllite (3G) marginal to 5A graphitic phyllite.


Topo Position:
Slope north of Willow Creek and east of Gravel Creek.

Soil and Sedimentary Notes:
Parent material seems to have B-horizon mixed in near bottom of A-horizon.  Duplicate site.


Topo Position:
Upper side valley slope above tributary to Willow Creek.

Bedrock:
Mt. Mye Fm - non-calcareous phyllite (3G)


Topo Position:
East facing slope on hill south of Swim Lake.

Soil and Sedimentary Notes:
Accumulation of pebble sized clasts immediately below the B-horizon.  Duplicate site.

Bedrock:
Van. Fm 5BCD - calcareous phyllite, metabasite and chloritic phyllite.


Topo Position:
Top of low, flat ridge off east end of Moose Lake.

Bedrock:
Mt. Mye Fm - non-calcareous phyllite (3g)


Topo Position:
East of Moose Lake near beginning of baseline that runs north of the lake.


Topo Position:
West of upper Moose Lake on east side of ridge (near top gentle slope)

Soil and Sedimentary Notes:
Oxidized soil.  Likely more distally derived.  May have to assay the -80 mesh fraction for low fines.  Bedrock at 60+


Topo Position:
Low flat ridge north of neck in Ghost Lake.


Topo Position:
Low ridge top between Finger and Swim Lakes.


Soil and Sedimentary Notes:
Dug into hoodoo and sampled till for fabric and geochemistry.  See field book.


Topo Position:
Top of low ridge North of east end of Moose Lake.

Soil and Sedimentary Notes:
Sample on linear topographic ridge dipping west.


Soil and Sedimentary Notes:
Ash layer varies in thickness up to 15 cm.


Topo Position:
South of the west end of Cub Lake on topo ridge trending west-southwest.

Soil and Sedimentary Notes:
Irregular ash/B-horizon contact, suggesting ongoing or paleo cryoturbation.


Soil and Sedimentary Notes:
15 cm sandy or gravelly sand bed encountered above till.  Site topographically flat.  Minor evidence of cryoturbation.


Soil and Sedimentary Notes:
Ash layer is discontinuous (0-22 cm).  B-horizon varies from 0-15 cm.  A-horizon is often a thin (0.5 cm) discontinuous line.  Textural change in till at 50 cm - olive grey to olive.  Stratified above/unstratified below (sampled) - sandier to siltier.


Topo Position:
Low ridge top on cut line south of Cub Lake.

Soil and Sedimentary Notes:
Pebbles dominant.  A few oxidized clasts noted.  Ash-A-B contacts are undulating.


Soil and Sedimentary Notes:
Bedrock is exposed on the front and sides of the crag and tail.  Boulders observed on surface.

Bedrock:
Van Fm. 5BCD - calcareous silcates, intrusive..)


Topo Position:
Low ridge top south of Swim Lakes near camp.

Soil and Sedimentary Notes:
Unusually thick B-horizon.  Numerous oxidized clasts.

Bedrock:

Topo Position:
West facing slope on ridge west of Sea deposit and east of Black Lake.

Soil and Sedimentary Notes:
Abundant chert pebbles, subrounded and subangular.


Soil and Sedimentary Notes:
Ash lyer shows slight colluviation.  15-24 cm:  coll. ash mixed with parent material.


Soil and Sedimentary Notes:
It appears that a veneer of coarse material brackets meltout at the surface.  At 63 cm clay content seems to increase.  Sample taken below 63 cm.
