MEETING CO-SPONSORS

We are soliciting sponsorships from local companies and individuals to keep meeting costs down, especially for students.  With one of longstanding goals of the ILSG being to attract students to the geology and mineral resources of the Lake Superior region, we want to make it as attractive as possible for students to attend both the meeting and the field trips.   We have identified several sponsorship options that we hope you will consider:

1) Sponsor travel and meeting support for students 

2) Sponsor part of the welcoming reception scheduled for Wednesday evening, May 4th 

3) Sponsor the extra cost of printing the guidebooks in color

See the SPONSOR REQUEST for more details

If you would like to be a sponsor of the 62nd ILSG, contact Christian Schardt (cschardt@d.umn.edu /218-726-7899) by April 15th.


FIELD TRIPS

Field trip registrations will be accepted on a first come-first served basis. The number of registration slots remaining will be given on Eventbrite registration site.  Based on the Indication of Interest forms recieved, most of the field trips are likely to fill, so register early to guarantee your spot.

IMPORTANT NOTICE: If you sign up just for field trips, and do not also register for the meeting, you will be put you on a wait list until April 20.  We give preference on the field trips to those also registering for the meeting.   If field trip slots are available as of April 20th, wait-listed registrants will be added to the remaining slots on a first-come, first-served basis.   If there are no slots available, you will be refunded the full field trip registration amount.  So if you want to guarantee a slot on a field trip, you should also register for the meeting.

All field trips depart from and return to the Duluth Entertainment and Convention Center. Participants must arrive at least 20 minutes prior to departure time (coffee will be provided). 

Lunches and beverages will be provided on all full-day field trips.   Rock (and till) sampling will be allowed at most stops, however, sample bags will not be provided. Trips will run, rain or shine, so be prepared for all weather conditions. 

PRE-MEETING FULL DAY FIELD TRIPS—WEDNESDAY, MAY 4

1) Glacial Geology of the Laurentian Uplands
Trip Leaders: Phil Larsen (Vesterheim Geoscience PLC) and Howard Mooers (UMD)

This field trip will explore the glacial geology of the highlands north of Lake Superior, an area straddling the transition from the thick drift characteristic of the southern margins of the Laurentide Ice Sheet to the scoured bedrock of the Canadian Shield. Recent high resolution lidar-derived topographic mapping has revealed a variety of small-scale landforms that have refined and expanded understanding of the timing of glacial retreat and sub- and pro-glacial processes acting on this landscape during ice sheet retreat. This trip will visit ice-walled lake plains, relict thermokarst features, ice-contact outwash, and Rogen moraine, as well as evidence for the extensive pre-glacial saprolite mantling shield rocks.
Attendance Limit – 24
Cost - $40

2) Neoarchean Geology of the Western Vermilion District
Trip Leaders: Mark Jirsa, Terry Boerboom, and Amy Radakovich (Minnesota Geological Survey)

This field trip includes both classic and newly mapped exposures of the Ely Greenstone, Soudan Iron Formation, Giants Range Batholith, and Lake Vermilion Formation.  It takes a preliminary look at stratigraphic relationships between the older rocks (~2720 Ma) and the apparently 30 Ma younger, locally conglomeratic sedimentary strata.  New mapping and recently acquired geochronologic data indicate the sediments of the Lake Vermilion Formation were deposited unconformably on the older, deep-water volcanic rocks, and imply that the formation represents deposition in a Timiskaming-type successor basin.
Attendance Limit – 40
Cost - $55

3) Cu-Ni-PGE Deposits of the Duluth Complex
Trip Leaders: Mark Severson (Teck American), Andrew Ware (PolyMet Mining), and Kevin Boerst (Twin Metals Minnesota), Steve Geerts (UMD-NRRI)

This field trip will focus mainly on drill core from the NorthMet, Mesaba, and Maturi Cu-Ni+PGE deposits that are hosted by the Partridge River, Bathtub, and South Kawishiwi intrusions of the Keweenawan Duluth Complex. These deposits are controlled by PolyMet, Teck, and Antofagasta; respectively. PolyMet is in the permitting process with state and federal agencies. Specific items to be displayed in the core will focus on mineralization styles as related to respective intrusive stratigraphies and footwall-related controls.
Attendance Limit- 76
Cost - $55

PRE-MEETING AFTERNOON FIELD TRIPS—WEDNESDAY, MAY 4

4) Duluth Stream Geomorphology and the June 2012 Flood - CANCELLED
Trip Leader: Karen Gran (University of Minnesota Duluth)

5) Geology of the Endion Sill, Duluth
Trip Leader: Jim Miller (University of Minnesota Duluth)

Just a 30-minute walk north of the Canal Park area along Duluth’s Lakewalk are the “Endion Ledges”.  The next mile of wave-washed shoreline outcrops traverse a cross section through the Mesoproterozoic Endion Sill, first studied by Ernst (1960).  Exposures reveal a complex history of multiple magma emplacement and varying degrees of country rock contamination between an andesitic lava flow footwall and a thick rhyolite hanging wall. 
Attendance Limit – 20
Cost -$10

POST-MEETING EVENING FIELD TRIP—FRIDAY, MAY 6

6) Geology and Trout Fishing along Amity Creek, Duluth
Trip Leader: Dean Peterson (Peterson Geoscience, LLC) and George Hudak (UMD Natural Resources Research Inst.)

Join us for a late afternoon/early evening trip up Amity Creek as we explore the varied geology and lore of stream trout fishing up Seven Bridges Road.  This field trip explores Mesoproterozoic lavas (Lakeside lavas and a series of icelandite flows) and diabasic intrusions (Northland sill and unnamed diabase dikes) in almost continuous exposure along Amity Creek. True stories and trout fishing lure recommendations will be discussed for those interested in hooking both rainbow and brook trout. The trip will culminate in a backyard barbeque at the Hudak’s Lakeside neighborhood home where additional geological discussions and fishing tales/lies may be told. Vans will pick up registrants from the DECC at 4:30PM and will return them around 9PM.
Attendance Limit - 32
Cost - $25

POST-MEETING FULL-DAY TRIPS—SATURDAY, MAY 7 (and SUNDAY, MAY 8 for TRIP 7)

7) Archean and Proterozoic Geology of the Western Gunflint Trail (Two-Day Trip)
Trip Leader: Mark Jirsa (Minnesota Geological Survey)

This field trip along the western end of the Gunflint Trail explores Neoarchean, Paleoproterozoic, and Mesoproterozoic rocks, and a diversity of well displayed unconformable and intrusive contact relationships.  The trip and this field guide are modified from the ill-fated 2007 ILSG trip that was canceled due to outbreak of forest fire. In this area, the Neoarchean greenstone-granite terrane of the Wawa subprovince of Superior Province is represented by a succession of metavolcanic rocks (~2720 Ma), intruded by the Saganaga Tonalite (~2690 Ma) and Proterozoic diabasic dikes. The Neoarchean and diabasic rocks are unconformably overlain by Paleoproterozoic sedimentary strata of the Animikie Group (~1870-1830 Ma), which includes the Gunflint Iron Formation.  The stratigraphic top of the iron-formation is marked by seismically deformed and brecciated strata and ejecta—known collectively as the Sudbury Impact Layer—that resulted from a meteorite impact near Sudbury Ontario (~1850 Ma).  A disconformity separates the impact layer from overlying siltstone and graywacke of the Paleoproterozoic Rove Formation (~1835 Ma).  Mesoproterozoic rifting is manifest in hypabyssal dikes and sills of the Logan intrusions (~1115 Ma), and several phases of the Duluth Complex (~1100 Ma), emplaced into both Archean and Paleoproterozoic rocks.
This 2-day trip departs Duluth on Friday late-afternoon, and returns to Duluth on Sunday evening. Two night lodging (double occupancy) with a continental breakfast and bag lunch on Saturday and Sunday is provided.   Those wishing to continue north after the trip on Sunday may drive to Grand Marais Friday afternoon.  Expect considerable hiking on trails and dress for variable weather conditions.
Attendance Limit – 38
Cost - $210

8) Keweenawan Geology of the Hovland Area
Trip Leader: Terry Boerboom (Minnesota Geological Survey) and John Green (University of Minnesota Duluth)

This trip will focus mainly on the upper, normally-polarized, northeast sequence of the North Shore Volcanic Group in northeastern Minnesota, but will also include some stops in the lower (reversely-polarized) part of the sequence, as well as examine some intrusions of the Beaver Bay Complex.  The trip will depart on Friday after the technical sessions have ended (~4PM) and we will overnight in Grand Marais, which is about a two-hour drive from Duluth.  Friday night lodging (double occupancy) and a continental breakfast and  bag lunch on Saturday will be provided.  The first stop on Saturday will be about 25 miles northeast of Grand Marais, near Hovland, and the trip will end up back in Grand Marais Saturday afternoon.  Those wishing to continue north after the field trip instead of returning to Duluth may drive their vehicles to Grand Marais the evening before the trip.
Attendance Limit – 38
Cost - $120

9) Duluth Harbor Geologic History Boat Cruise:  Quaternary to Anthropocene
Trip Leaders: Irv Mossberger, Mehgan Blair, Eric Dott (Barr Engineering), Andy Breckenridge (UW-Superior), Todd Kremmin (UMD)

Join us for a tour of Lake Superior and the Duluth Harbor via excursion boat.  Your guides will review the geologic history of Lake Superior and the St. Louis River estuary, and the context in which modern industrial environmental issues occur. View sediment cores on the boat, with side trips via land to Park Point beach dunes, and a tour of the Blue Heron research vessel.  
Attendance Limit – 40
Cost - $30

Questions about field trips, contact Dean Peterson (dpeterson1000@gmail.com) or Jim Miller (mille066@umn.edu)

Post- Post-meeting PRC Field Trips (details coming soon)

To celebrate the past nine years of the Precambrian Field Camp sponsored by UMD's Precambrian Research Center, several weekend canoe-based field trips will be offered throughout May that will highlight the geology mapped during various capstone projects. Capstone mapping projects, conducted during the fifth week of camp, were the highlight of the Precambrian field camp. The projects involved 2-5 students and an instructor conducting detailed bedrock mapping in poorly mapped locations within or near the Boundary Waters Canoe Area Wilderness (BWCAW) in northeastern Minnesota.

Most field trips will involve travel through the BWCAW. Because a maxiumum of 9 people in 4 canoes can travel together in the BWCAW, these trips will have limiited availability. The tentative list of possible field trips to be offered include:

Sawbill Lake Intrusion of the Eastern Duluth Complex - Jim Miller, Adam Leu, Ben Brooker

Wilder Lake Intrusion of the Central Duluth Complex - Adam Leu, Jim Miller

Bald Eagle Intrusion of the Central Duluth Complex - Dean Peterson

Archean Knife Lake Group in the Disappointment Lake Area - George Hudak
