This map covers much of same area as Goad's did in the previous post. The brown contour lines are calibrated in metres above sea level (ASL) — all contours, including the light brown "minor" lines, are two metres apart. As always, click on the image to view large.
You can see two yellow patches on the map. They don't exactly match the yellow areas on Goad's map but they are related. The lower patch is that part of Nanny Goat Hill which rises beyond 80 metres ASL. The upper patch is Parliament Hill, where the elevation reaches the 80 metre mark just north of Wellington Street — think of the embankments directly behind the stone and iron fence. Three minor contours looping across the Parliamentary front lawn confirm that the Centre Block is built on an 86 metre ASL plateau. No other ground on this map reaches, let alone exceeds an 80 metre elevation.*
The red triangle demarks this walker's subjective impression of all that is NGH, its shape roughly echoing the "yellow tongue" we saw in the last post. The lower right corner of this triangle sits at the northwest corner of Dundonald Park, where a gentle rise that began near Bank Street flattens off noticeably. The top corner, as we've already seen, sits at the junction of Bronson and Laurier Avenues. On the west... well, that cliff is hard to ignore. And as to the bottom left corner, things do start to drop away somewhat around Empress and Arthur — by the time you reach Somerset and Booth, it's all downhill with a vengeance.
Oh, and I think I figured out where that "Nanny Goat Hill" restaurant whatever thing used to be, back in the '70s — it looked bigger back then.
