Slope soaring on the Cathederal Ranges in the Phoenix motorglider

Not the greatest of soaring days, but I was cruising (motoring) past the Cathederal ranges and thought I would see if the slope soaring was working.
I think this was as much thermals being triggered as slope lift, but it's all fun. Another example of how the Phoenix gets you places you don't normally get to soar.
I have driven past this range many times and imagined it would be great for ridge soaring but rarely find the right conditions for it to be working.
