Surveyor Spur alternative

Access to an alternative route onto Surveyor Spur, starting from O31 659 850 / BT27 559 234, appears no longer possible after the 2016 earthquake. The route was as follows: At a large cairn before the first major tributary on the true right, look for a plastic road marker pole. Initially follow through fern, then move left onto a steep open slope with tussock and scrub. Keep left of all major slips. From a small grass terrace, climb through alpine shrubs, lightly cut. Occasional poles mark the route, however most are not visible from above, hence this route is difficult to follow as a descent, especially if snow covered in the alpine scrub section. Then follow a narrowing ridge. At about 1300m is a small open bivvy site (no water). The route meets the main Surveyor Spur just above the 1940m campsite.
