The evening will be structured around a photo tour of the 2021 field trip season, emphasizing specimens collected. We’ll tap into our collective knowledge to understand the sites and fossils found.
To participate:
Review the list below of sites/formations visited in 2021,
Dive into your collection and select a few corresponding fossils (many of you have visited these sites/formations over the years!),
Accept the Zoom meeting notice sent to paid VicPS members, and
Show up, share the specimens and knowledge you’ve collected over the years, and help identify specimens.
Field Trip participants, please have your specimens on hand for show and tell.
As an alternative to our cancelled field trip of Nov 21, VicPS President Jerri Wilkins has had Dino Lab offer to give VicPS members a tour at 4 PM tomorrow, Sunday Nov. 21, for $32 a person. That price is a 20% discount from their standard entrance fee. We can take up to 10 people.
Anyone who wants to go will need to pay their own fee and RSVP Jerri in advance by email.
The planned November 21 field trip is cancelled, or possibly postponed to another date. Malahat traffic is presently one-way alternating, 24/7, and is intended for essential travel.
Instead, we are planning a VicPS tour of local fossils, for members only, with details to be announced. Stay safe, and stay tuned!
Where: Please see email to registered members for location details.
We are revisiting the second site from the September field trip to investigate further. It consists of a few pits, appeared to be created by blasting. In September the hard matrix revealed brachiopods and what appear to be trigonids.
Site suitable for families.
Travel: Meet at Helmcken Park & Ride at 9 am to arrange carpooling.
Equipment: The rock is TOUGH, with fossils in bedrock, not concretions. Bring your big hammers, chisel, safety glasses and gloves. Big boulders can be slippery; hiking boots recommended. Bring drinking water and bag lunch. Dress for rain, wind or sunshine (windbreaker, hat, sunscreen).
Exposure: Upper Cretaceous (90MY before present), Nanaimo Group, Upper Comox to Lower Haslam Formations. This small exposure of Nanaimo Group sediment is gritty sandstone/mudstone similar to Stephenson Point and thought to be Upper Comox to Lower Haslam in age, although no definitive reference could be sourced.
Where: A benefit of membership is the email describing this trip. The sites to be visited are easily accessible and suitable for families.
Exposure: Upper Cretaceous (90MY before present), Nanaimo Group, Upper Comox to Lower Haslam Formations.
Directions: Victoria area members, meet at Helmcken Park & Ride at 9:00 am to arrange carpooling. Members from up-island may join the trip in Duncan when we stop at Java World for a coffee between 9:45 and 10 am.

Fossils: Fossils that may be found are:
Ghost shrimp claws – Callianassa
Bivalve – Inoceramus
Heteromorph Ammonite – Eubostrychoceras elongatum, mostly fragments and Glyptoxoceras subcompressum
Planispiral Ammonites – Epigoniceras epigonum, Hauriceras gardeni and Gaudriceras striatum
Nautiloid – Eutrephoceras campbelli
Lobster carapace – Linuparis, up to 6-8 cm
Limpet – Capulus corrugatus (uncommon)
Gastropod – Tessarolax distorta (rare)
Flora – unidentified leaves
Directions: Meet at Helmcken Park & Ride at 9:00 am to arrange carpooling.
Equipment: Minimal collecting equipment includes a geological hammer, chisel and safety equipment (gloves and goggles — safety helmet advisable). Footwear should be suitable for wading and walking on wet stones. Bring water, a lunch, and gas money if you’re carpooling. Sun protection may be warranted, too.
Directions: Meet at Helmcken Park & Ride at 8:00am. COVID-19 protocols remain in effect; masks during meet and greet and travel via separate vehicles.
Exposure: Dumont Road is the site of two quarries containing exposures of the Late Cretaceous Haslam Formation, where beautiful white fossils of the the ammonites Canadoceras and Pseudoschloenbachia, numerous bivalves and gastropods and other diverse fossils have been found, along with occasional plant material. The lower of the two quarries is now a motocross track and practice may be taking place so awareness and caution are needed. The upper quarry hasn’t been excavated in many years, but preserves a slightly different fauna – perhaps younger? – than that of the lower quarry.
Equipment: Fossils are found in the rock and in concretions, so a good hammer or sledge, chisel, and protective eyewear are required. It’s a hillside, so expect to ascend and descend slopes with some significant elevation gain, with some uneven footing, but as sites go, it’s an easy walk. Dress for the season and bring lunch and water.
Directions: Meet at Helmcken Park & Ride at 9 am. Carpooling optional/personal decision; masks must be worn if/while carpooling, social distancing mandatory throughout the field trip.
What will I be collecting? East of Duncan lies Mount Tzouhalem, a high point of land that overlooks Cowichan Bay. Much of the mountain is forested, and some of it is protected by an ecological reserve, but the northern side of the mountain has been subdivided and has many residential properties. At the top of the mountain an enormous area was cleared and landscaped to become a golf course, but the failure of the development means that the part of the hill is now being turned into housing as well. Fossils at this locality are characteristic of the older part of the Haslam Formation, including the typical ammonites heteromorphs (Haeuriceras, Eupachydiscus, and the heteromorphs Eubostrychoceras and Glyptoxoceras), and a wide variety of clams and snails. Along with the more standard fare, the exposures here have yielded some rarities, such as the crinoid Uintacrinus and the spiny ammonite Urakawites, which are unknown from most other Haslam localities. Preservation of shell is typically black in colour.
What should I expect? Access to Mount Tzouhalem is good, we can drive to within a few minutes’ walk of the best exposures, but because it is a hillside you should expect to ascend and descend slopes with some significant elevation gain. We will be targeting large piles of boulders created on a few locations on the hillside (because this tends to be where erosion takes place), so you could also be walking on slightly uneven footing. Because there is just so much of the mountain to explore, everyone should be able to find an area to suit them, and for this reason I can recommend Mount Tzouhalem to collectors of all ages and activity levels. Fossils are found in the rock and concretions, so a good hammer or sledge, chisel, and protective eyewear are required. Be aware that this is the site of a former excavation, so you should expect to be walking on rocks and boulders that can be slippery and treacherous.
Why should I come on this field trip? Fossils are not especially common on Mount Tzouhalem, either in the rock or in concretions, but because there is just so much rock exposed here we usually have some finds. The VicPS has been collecting on Mount Tzouhalem for several years, and with excavations no longer occurring there we may not find as much fresh rock as we used to, but there are still many fossils to be found. The diversity of the Cretaceous fauna at this locality, the chance to find a rare or unusual fossil, and the beautiful views of the Cowichan Valley always make Mount Tzouhalem an attractive choice for fall and winter collecting.

Exposure: Cliffs along the deep canyon of the Chemainus River expose the black mudstones of the Haslam Formation, an ancient marine environment deposited in the Upper Cretaceous (85MY before present). Fossils can be found high above on the cliff face and loose in the steep piles of scree stretching to river level. Fossil are common in large and small concretions and in situ on this stretch of the river.
Many of the fossils of the Haslam Formation are representatives of extinct animal groups which have no modern counterparts. The ancient Haslam environment was a shallow sea populated by molluscs, fishes, and giant marine reptiles. Some of the fossils, such as clams and snails, are similar to their modern relatives, but others, such as the extinct ammonites, provide an excellent opportunity to explore changing life and environment over geological time.
