Geology Section
Chair: David Cook cookeco2@yahoo.com 604-924-0147

The	Nature	Vancouver	Geology	Section	conducts	field	trips	
throughout the Vancouver region during the year. The present
Geology Section is a relatively recent reintroduction of a Section
that was strong in former years of Nature Vancouver.

In	most	instances	the	geology	field	trips	also	include	
observations on the ecology of the area visited, the purpose
being to show the relationship between natural ecosystems and
the substrate upon which they depend.

The Geology Section also has an ongoing program of compiling
outlines	of	self-guiding	geology	field	trips.	These	can	be	found	
on the Nature Vancouver website.

For	details	of	the	geology	field	trips	refer	to	the	Field	Trips	
section of Vancouver Naturalist and the Nature Vancouver
website.

              NATURE VANCOUVER
                SUMMER PICNIC
                    SUNDAY, JULY 10, 2011
        at Lighthouse Park in West Vancouver
Nature Vancouver is hosting a summer picnic at Lighthouse
Park, a federally owned park leased to the Municipality of West
Vancouver. It is approximately 40 minutes from downtown
Vancouver by public transportation and 20 minutes by car.
Lighthouse Park marks the point where Burrard Inlet meets
Howe Sound. It is an example of the transition from the dry
Coastal	Douglas-fir	Zone	to	the	wetter	Coastal	Western	Hemlock	
Zone.	The	park	has	the	largest	Douglas-fir	trees	in	Greater	
Vancouver, and has the largest uncut, coastal-elevation trees
in the Lower Mainland. It has spectacular views of the water,
Stanley Park and the city to the east, Bowen Island and the Strait
of Georgia to the west.
Where to meet: Phyl Munday Hut approximately 10 minutes
from the parking lot (map at info board at entrance to the park).
How to get there: The park is serviced by public transportation.
Visit the following webpage for driving and transit directions;
http://www.vancouvertrails.com/trails/lighthouse-park/#transit.
(Transit	directions	should	be	verified	by	contacting	Translink.	
Also refer to Nature Vancouver’s book, Parks and Nature Places
Around Vancouver. There is parking just inside the entrance to
the park. Access is from Marine Drive via Beacon Lane.
Time: Trail walks start at 10:00am. Picnic is at noon 12:00pm
to 2:00pm. Members can mingle at the Hut until 3:00pm.
Afternoon trail walks start after 2:00pm.
Elevation: The trails are all fairly easy with only a few having a
short hill to ascend or descend. Trails can be muddy, and rocky
areas and roots are slippery due to the damp microclimate. Wear
appropriate walking shoes.
The picnic: Takes place at the Phyl Munday Hut between
12:00pm and 2:00pm. The hut will provide shelter for us from
any inclement weather and function as an outpost (starting point)
for our scheduled walks. It has a kitchen but please bring your
own implements. Nature Vancouver will provide beverages and
fruit	plates.	Please	bring	finger	food	to	share	with	other	members	
and your mug/plate, if you can. Bring your enthusiasm. Come
for the walks and the picnic, or, just come for the picnic and a
chance to socialize with fellow nature enthusiasts. Join us! Rain
or shine! Everyone is Welcome!
Guided Walks: Several of our members will be leading nature
walks	and	talking	about	the	western	red	cedar	and	Douglas-fir	
old growth trees, forest ecology, bird life, intertidal/marine life,
coastal bluff ecology, geology, and the invasive plant removal
and native plant restoration programme. The walks are scheduled
to take place before and after the picnic.
For more info, ideas you would like to share, ways you can help
out,	finger	food	you	can	bring,	and	if	you	will	be	attending,	
please contact Nellie at nellieba@telus.net. By contacting us
we can plan accordingly. Keep checking the Nature Vancouver
website, as more details will follow.

THE	BIZARRE	LIFE	OF	BARNACLES	was	the	title	of	our	
outing at Jericho Sailing Centre with Sheila Byers in April. As
usual	she	provided	a	most	interesting	program,	first	an	exciting	
overview of the life of one of Charles Darwin’s favourite marine
organisms – the barnacle. From goose Barnacles to acorn
Barnacles to parasitic barnacles, we discovered the interesting
natural history, life cycle and ecology of these curious animals.
Such odd names, odd shapes and such peculiar behaviour! To
appreciate their structure Sheila and her assistants helped us
create some original artwork to mimic the shape of the common
acorn barnacle. We had lots of fun folding the colourful paper
into weird shapes that represented barnacles. After the indoor
program, we moved from the classroom down to the wooden
Crab pier at Jericho beach and explored the live barnacles and
other small creatures living in the water and the nearby rocky
outcrop. It was a very interesting day.

In May we learned about CATERPILLARS from PhD candidate
Heather Kharuba and Dr. Judy Myers of UBC. It was a rainy
morning and not too many members turned up, but those
who came had a great time learning about the life cycle and
adaptations of tent caterpillars. Many caterpillars resemble the
plants which they feed on or may even have parts that mimic
plant	parts	such	as	thorns.	After	a	short	fieldtrip,	we	moved	into	
the greenhouses of UBC where Judy and Heather provided us
with several interesting games of learning about the needs of
caterpillars and the type and strength of leaves they feed on.
We were also shown several different types of larvae under
