#Terracotta #TrueScale #GISDay and the Visionaries #maquette dropped in for an orientation session.

#RiverLot5 #Treaty6
The Visionaries (maquette) Artist Barbara Paterson While the statue presents a conversation between the two university founders about the location of the proposed university, there is a deeper, layered history that the statue overlooks. The map held by Rutherford depicts a section of land marked with the number 5, which would become the future home of the University of Alberta. This map illustrates the presence of Métis river lots and specifically marks River Lot 5, along the south bank of the North Saskatchewan River. River Lot 5 was also a place where the Laurent Garneau family lived, played and made a living. River lots were included in the 1882 Dominion of Canada Survey for the settlement of Edmonton, Northwest Territories. The statue, however, provides limited visual information on who was present on the land and suggests that it was uninhabited before the university’s establishment. The history of these lands, prior to European contact in western Canada, included Niitsitapi (Blackfoot), Dene, Néhiyaw (Cree) and Stoney Nakoda Nations. There would have been agreements or treaties in place between these Nations around sharing of the land. In essence, the statue simplifies the layered history of the land and points to the erasure of First Nations presence, of Treaty Six (signed in 1876) history, and the disenfranchisement of the Papaschase Cree Nation and their reserve (No. 136) lands. Large statues such as “The Visionaries” serve to publicly affirm the history and authority of those who are portrayed in the work. Although intended to celebrate the institutional founding of the University of Alberta, the statue brings to light the importance of acknowledging Indigenous Peoples and lands, and the way complex and layered histories are remembered and commemorated on campus. This is the endeavour of the people who continue to work and study at the University of Alberta today.

A request for historical maps of the Edmonton River Valley turned up this 1978 Capital City Recreation Park brochure (tabloid size!) archive.org/details/WCWd...
Lots of interesting planning and river valley history (Water Quality, Bank Stabilization, and the infamous Strathcona Science Park, ect.)
Cover of the 1978 Capital City Recreation Park [publicity brochure] Notes: It was to provide improved recreational opportunities for all Edmontonians, as well as to upgrade river facilities before the 1978 Commonwealth Games, that the Alberta government decided to provide about $34 million for a parks development in the river valley of east Edmonton. Most of the planning and development for this river area, now known as the Capital City Recreation Park, is complete. It complements the city’s 1970 master plan for parks development and provides funds for trails, landscaping, shoreline stabilization, public use amenities, a science centre, four pedestrian bridges, fresh water lagoons, and property acquisition within two narrow strips on both banks of the North Saskatchewan River. The vision, to provide a recreation playground in the river heart of a rapidly growing and modern city, is not a new one. As early as 1907, the city council of that era entertained a report by Frederick G. Todd, a landscape architect from Montreal, that designed a plan for parks and boulevards in Edmonton. It recommended ... “every advantage should be taken of the great natural beauty of the situation . . . by withdrawing for parks purposes, property, such as the river valley and ravines.” Mr. Todd’s recommendation for a river valley park system was accepted and adopted into the 1915 city plan. In 1933, the city zoned much of the area for use as a “public park”, introducing land use regulations to that effect. A further report, the Bland-Spence Sales Report, was adopted in principle by city council in 1949. It recommended a “comprehensive system of parkways’’ throughout the whole river valley and proposed a system by which development in the river valley could be opposed. This was first implemented in 1951 when council approved a plan showing Rossdale Flats as proposed parkland. [map] Overall Plan, Trails and Improvements in the 1978 Capital City Recreation Park Shows: RESTRICTED DEVELOPMENT AREA WATER CONSERVATION AREA BIKEPATH HIKING TRAIL FOOTBRIDGE UNDERPASS TOEBERM AMENITIES STRUCTURES AND PARK BUILDINGS PARKING LOTS From the 1978 Capital City Recreation Park [publicity brochure] Capital City Recreational Park Opening Day Activities, July 9, 1978. From the 1978 Capital City Recreation Park [publicity brochure] Strathcona Science Park forms the most easterly node of the Capital City Recreation Park plan, and will provide a dynamic new provincial educational and cultural facility in a beautifully landscaped provincial park. Strathcona Science Park is located on the eastern side of the North Saskatchewan River in the County of Strathcona, adjacent to the eastern gateway to the city. at Highway No. 16. The Strathcona site is about 2 kilometres in length and up to 1,500 metres in width. It comprises a high plateau with steep slopes dropping down to the river, affording commanding views of the river valley, downtown Edmonton and petrochemical industries nearby. The 350-acre site is a key element in the Capital City Recreation Park plan, providing for rehabilitation and beautification of a derelict site ringed by industry, which otherwise might adversely affect the Capital City Park concept. The planning of the park has been the responsibility of the Science Centre Committee, with Raymond Harrison, MRAIC, as the programming and development consultant. The concept of a river valley park fringing an industrial area is not only noteworthy in itself, but it provides a relevant setting for a natural resource science interpretive centre. As the first major cultural facility on the eastern side of Edmonton, it provides a balance to the museums and the historical and cultural attractions located in the western part. When fully developed, the south end of Strathcona Science Park will feature a nature interpretive area in the ravine and an extensive picnic area with well developed viewpoints. The Strathcona Science Park is being developed as a vital public educational institution in popular science and technology, for the purpose of enabling Albertans to better understand the rapid and complex changes taking place now and in the future.

Wall maps move again.
10 years ago they went from the old offsite storage "The BARD" (2nd pic) back to the library in the overflow storage area or The Elevator Room.

The richest appreciation one can have of a [wall map] is to know what prompted that conscious decision to put it there. (Ed Dahl)
William C. Wonders Map Collection, collection of Wall Maps. Moving from the overflow map storage area, fourth floor elevator room Cameron Library, to the Map Room. In 2016 we weeded the wall maps that were stored in the UAL's off site storage called "The BARD". All weeded wall maps (maps already in the collection as flat maps in cabinet drawers) went to Edmonton's Reuse Centre where by all accounts they were gone within hours after drop-off. This is essentially 1/3 of the original wall map corpus. Wall maps were the power-point of their day and valuable items for in-class teaching. Now they cover walls, or are used as curtains, and once and a while borrowed. This may look like a shamble of cloth backed spatial analogues but they go for a hefty price online. This is an image from 2016 These are the wall maps that were essentially returned to the community via Edmonton's Reuse Centre. These are wall maps that duplicated flat maps already stored in the William C. Wonders Map Collection map cabinets. It is interesting to think they are all now scattered across Edmonton doing what they do best - hanging around and filtering light.

According (Grunes 2021) it is through expedition leader Charles Wilkes, Melville explores the nonhuman sublime, its power to test human physical and epistemological limits, and the driving ambition it provokes. In the process, Melville extends Wilkes’s image of the “icy barrier” around Antarctica. This wall, barrier, or mask becomes an origin point for the ambitions—Ahabian, Ishmaelian, Wilkesian and even Melvillian—that energize epic endeavors, including those of the young republic’s nascent expansionist imperialism.

Ex.), commanded by the relentlessly ambitious Navy Lieutenant Charles Wilkes. When Wilkes led his ships south, it was unknown whether ice, land, or open ocean covered the South Pole. Within only a few weeks, the expedition had identified the existence of the continent; yet Wilkes had an even grander goal in mind: to land on the continent. For nearly two bitter months, his men mapped 1,500 miles of the coastline, seeking an opening in the icy barrier girding the continent. They never set foot on it." From - Grunes, M. (2021).

[quote] ... you would have seen him intently study the various lines and shadings which there met his eye; and with slow but steady pencil trace additional courses over spaces that before were blank. page 282 . [image of a journal article] Nègre, Julien. (2022). The World in a Footnote: Examining Ahab’s Chart in Chapter 44 of Moby-Dick. Miranda. No. 26 Melville’s Measures. https://doi.org/10.4000/miranda.47428 Abstract: Chapter 44 of Moby-Dick (“The Chart”) includes a footnote comparing Ahab’s plan to track Moby Dick across the globe with Matthew F. Maury’s efforts to chart the winds and currents of the oceans and produce an accurate “whale chart.” This article unpacks the effects produced by the addition of the footnote in the chapter and uses it as a starting point for examining Ahab’s charts and discussing the interactions between map and text. At first sight, Maury’s chart is used as a stable reference point that reinforces the verisimilitude of Ahab’s plan. A comparison of Ahab’s use of nautical charts with actual documents used by whaling captains, though, reveals a disjunction between his cartographic ratiocinations and Maury’s work. Yet the most significant detail in the footnote might be the fact that Maury’s chart is “in course of completion”: far from being a definite document that the text can rely on to bolster the plausibility of Ahab’s method, the chart remains unseen—and even unseeable, since the version described in the footnote was never produced in reality. The “deictic” gesture performed by the footnote duplicates Ahab’s yearning for an object that constantly eludes him.
