Description
Mesa Butte, also known as Square Butte, is a hidden gem in Alberta's free-flight scene. This rounded grassy peak in the foothills is perfect for soaring and thermals on Southeast days when other nearby sites are not flyable. The site is suitable for pilots of all levels, but a P3 rating or above is recommended during active spring thermals. If you manage to gain altitude, you'll be treated to views stretching from British Columbia to Calgary.
Access to Mesa Butte involves driving west past Millarville and parking at the wellsite entrance approximately 1.1 km past the Mesa Butte Equestrian Campground. Ensure you do not block the gate. From there, hike along the Mesa Grind Trail for 1.8 km with an elevation gain of 229 meters to reach the top.
The launch area primarily faces Southeast, but South and East launches are also possible depending on conditions. The launch is a grassy slope that is deceptively steep, making it susceptible to rotor. Position your launch as close to the edge as you can safely manage, especially on east-facing days when rotor can wrap around from nearby trees.
Mesa Butte is ideal for top-landing and side-hill landing. Be cautious of your ground speed, wind direction, and any hazards before attempting a top-hill or side-hill landing. If top-landing is not possible, there is ample grassy space at the bottom of the slope. Note that the grass can grow especially long during peak season. Pilots landing at the bottom can use the Mesa Traverse Trail to hike back to the top. On good days, some pilots have landed back at their cars, but ensure you have plenty of height and are aware of any hazards such as tripping hazards in the cut-block and overhead powerlines.
The takeoff and landing areas have no airspace restrictions. Slightly above launch, pilots will encounter the Calgary CAE (Class E) at 5,800 ft. HAGAR is required for flying in Class E airspace. Further up, the YYC Aerodrome (Class C) extends from 8,000 ft to 12,500 ft. Do not breach the 8,000 ft ceiling under any condition.
XC options at Mesa Butte are limited by overflying airspace. Pilots flying west will encounter fewer airspace restrictions but also fewer landing options and eventually the Provincial Park. Pilots flying in other directions must be cautious not to break the 8,000 ft barrier. It’s usually easiest to stay local at this site.
