announced an agreement to settle a land claim in the region of Castle Mountain, known as ''Miistukskoowa'' to the Siksika. The agreement ended an outstanding claim dating back to the 1880s when land located at Castle Mountain was set aside as a timber berth for the use and benefit of the First Nation. The basis of the claim was that these lands were wrongfully taken from the First Nation in 1908 without their consent and without proper compensation. In 1911, these lands at Castle Mountain were added to Rocky Mountain Park, now known as Banff National Park. The agreement provides the Siksika Nation with approximately $123 million in financial compensation, the option to purchase on the open market up to 17,491 acres of land outside of the boundaries of Banff National Park and apply to Canada to have the lands added to its reserve, economic opportunities inside Banff National Park, and ongoing park access for cultural, traditional and educational purposes. First Nation members voted to approve the settlement on March 4, 2016. Canada gave its final approval on August 15, 2016.

Scramble route

While the peak presents a formidable challenge to climb when viewed from the highway, the mountain can be ascended by first hiking to Rockbound Lake which is located on the easier backside. A break in a cliff band provides access to a route above the lake. The ascent is a very long day when undertaken from the trailhead and can easily require 12 hours for a return trip. This cannot be shortened as random backcountry camping is not permitted in the area. The Castle Mountain Hut on the southern side could be used but requires technical rock climbing skills and possibly a rope to access it. While the normal scrambling route reached via Rockbound Lake is primarily a long slog, there is no discernible trail once one reaches the top of the "big hill" overlooking the lake and requires moderate scrambling abilities and a bit of route finding to ascend the gully leading to the upper bench. If pressed for time or a different objective, Helena Ridge is basically a scree slog straight up although a lingering snowfield in the gully above the big hill may provide some relief. Snow patches often linger on the upper routes even in late summer so an
