Horsethief Falls is found in the Purcell Ranges, more than 50 km up Horsethief Creek.   It is in a remote spot, hidden in a canyon so it is not well-known.  There is no trail to the base of the falls and the faint trail to the top of the falls is unmarked and a bit of a scramble.   While hiking back from Lake of the Hanging Glacier, I looked for a trail and spotted traces of a route downstream to the brink of the falls.

I could not find any online sources that provided the height of the falls, but it tumbles down 3 contours, starting as a cascade and then dropping down the cliffs to the valley below.   My estimate is it is about 260m.

Horsethief Creek runs down through a gorge then tumbles over the first part of the falls, sending out a horizontal spray into the abyss below.

All of the views from above were on the edge of a cliff.   Looking straight down would have required the use of a rope and harness.

I climbed down as far as I could safely get to a viewpoint to take a photo, then returned by the same route which I used to get to the top of the cliffs.

On the way down to the trailhead I looked for a side trail that would lead to the base of he falls, but did not spot one.   The main trail passes close to the creek 1 km downstream and it would be a 0.5 km bushwhack up to the base of the falls from below, an ambitious venture if already hiking into Lake of the Hanging Glacier and back.
