Narrative:

A portion of our route included vvc UB689 bog UG447 spp. This route overflies high terrain with mountain peaks exceeding 13;300 feet. The planning guide; south america region section; does not include a terrain critical depressurization procedure for this route. Approaching vvc; we contacted dispatch and asked if the procedure may be located in another section of the guide. While waiting on the answer from dispatch; we considered a course change including a course reversal. Dispatch [could not suggest any specific publications that covered this route.] we proceeded on our dispatched and cleared route with great caution. We discussed contingency plans for possible mechanical failures requiring a descent.
