Crosswinds always make for interesting landings, but they can get especially exciting at this runway, in particular. Runway 17/35 doesn't run parallel to the SLC's other two main runways, but in order to keep enough space between planes landing on different runways, the approach paths to all three have to be parallel. This means that aircraft landing on 35 have to approach at an offset angle, then turn at the last minute to line up with the runway. When you add strong gusts of wind pushing you sideways to that maneuver, things can get a bit tricky, as seen in this video.

I want to emphasize, however, that the all of the pilots handled these difficult landings perfectly well. While the weather made things a little more exciting than usual, these were not dangerous situations and I'm confident no one's lives were at risk.

Runway 17/35 is generally only used for airline traffic when the center runway (34R/16L) is needed for takeoffs, so after the last plane in this video landed, they switched to the other two runways because the departures had died down by that point.

Here's the full list of aircraft seen in this video; it's mostly Delta morning arrivals from the Midwest & Eastern US, plus one business jet:
