Environment - Non Weather Related; Procedure
On the Delta 5 Arrival inside of SPIEK waypoint; we were in trail of a 737; 10 miles or so ahead; when we were hit with wake turbulence. It caused us to roll to an approximate 70 degree bank to the right; at which time I disconnected the autopilot [and] rolled wings level. I added power and began a climb to 15;000 feet. I contacted SLC Approach and advised that we were in wake turbulence and that I was climbing to 15;000 feet. They cleared me direct PITTT waypoint; which I refused; trying to avoid more wake issues. I flew a heading until I felt comfortable proceeding to PITTT waypoint.
CE525 Captain reported encountering wake turbulence on arrival into SLC from a preceding B737 that resulted in a 70 degree bank.
