CORP ACFT DEVIATED FROM SID.

Narrative

WE WERE GIVEN CLRNC TO DEPART RWY 35 AT SLC AND FLY THE SLC5 DEP; TO INTERCEPT THE SLC 094 DEG RADIAL; TO JOIN THE MTU 303 DEG RADIAL; MTU DIRECT JNC; DIRECT ALS THEN AS FILED TO IAH. THE DEP IS A VECTOR WITH A REQUIREMENT TO MAINTAIN A 340 DEG HDG AND CLB TO 8000 FT TO CROSS 7.5 MI N OF SLC VOR AT THAT ALT. AS SOON AS WE WERE AIRBORNE AND CONTACTED DEP; WE WERE GIVEN A CLRNC TO FL230 AND WERE STILL S OF THE SLC VOR AND THE 094 DEG RADIAL. I THEN ASSUMED THAT THE RESTR AT 8000 FT AT 7.5 MI N OF THE VOR HAD BEEN DELETED BY THIS CLRNC AND THAT I SHOULD CONTINUE CLBING TO FL230 AND SHOULD TURN R AND JOIN THE 094 DEG RADIAL OF SLC; WHICH I DID.SHORTLY AFTER ROLLING OUT OF THE R TURN; DEP CALLED AND TOLD US WE WERE SUPPOSED TO MAINTAIN RWY HDG AND 8000 FT AND QUESTIONED IF WE WERE WILLING TO PROVIDE OUR OWN TERRAIN SEPARATION. WE SAID WE WERE ABLE AND WILLING TO PROVIDE OUR OWN TERRAIN AND TOLD THE CTLR THAT WE HAD BEEN CLRED TO FL230 AND THOUGHT WE WERE SUPPOSED TO JOIN THE SLC 094 DEG RADIAL. HE REPEATED THAT WE WERE SUPPOSED TO MAINTAIN RWY HDG AND 8000 FT BUT TOLD US TO CONTINUE ON THE 094 DEG RADIAL SINCE WE HAD AGREED TO PROVIDE OUR OWN TERRAIN SEPRATION. I REALIZED MY ERROR IN NOT CONTINUING THE SID AS PUBLISHED AND NOT CLBING TO FL230 UNTIL AFTER PASSING THE 7.5 MI FIX N OF SLC VOR; BUT IT WAS VERY CONFUSING AT THE TIME. THE CONFUSION WAS ONLY MADE WORSE BY THE WAY THE EVENTS HAPPENED; BUT THE ERROR WAS ALL MINE AND I HAVE NO EXCUSE. THE FACT THAT THE DEP HDG CROSSED THE 094 DEG RADIAL OF SLC; ALLOWED ME TO CONVINCE MYSELF THAT I SHOULD JOIN IT. IN ADDITION; WE WERE EASILY OUTCLBING THE HIGH TERRAIN TO THE E AND WOULD HAVE BEEN WELL CLR OF IT ON THE 094 DEG RADIAL ON OUR WAY UP TO FL230. THE WHOLE SIT WOULD HAVE NEVER HAPPENED; IF I HAD JUST ASKED FOR VERIFICATION PRIOR TO MAKING THE TURN AND CONTINUING THE CLB. STUPID!
