Timberline Lodge Mt Hood Shining

where was the filming location inside of the hotel and out in the hedge maze in the shining?
it seems pretty common knowlege that the outside shots were filmed at timberline lodge near mt hood. And I know part of it was shot at studios in england. but does anyone know where the inside of the hotel and hedge maze were filmed?
All of the interior rooms of The Overlook Hotel were filmed at Elstree Studios in England, including The Colorado Lounge, where Jack does his typing. Because of the intense heat generated from the lighting used to recreate window sunlight, the lounge set caught fire. Fortunately all of the scenes had been completed there, so the set was rebuilt with a higher ceiling, and the same area was eventually used by Steven Spielberg as the snake-filled Well of the Souls tomb in Raiders of the Lost Ark (1981).
The making-of documentary shot by Vivian Kubrick shows that the hedge maze set, while nowhere near as large as the maze in the film (which was mostly a matte painting), was still large and complex enough to require a detailed map. In the commentary for her documentary, she notes that many crew members really got lost in the maze, dryly noting that it now reminds her of the lost-backstage scene in This Is Spinal Tap (1984).
