The shovel shear test provides information about the location where the snow could fail in shear. It is best applied for identification of buried weak layers and does not usually produce useful results in layers close to the snow surface. Soft snow near the surface is better tested with the tilt board and the shear frame or an improvised version of this tilt test.  3, record 1, English, - shovel%20shear%20test

Shovel Shear Test. This test can be done on a flat or on a slope. With good technique, the location of weak layers, even thin weak layers, can be found. First dig a hole or pit in the snow. The vertical wall of the pit should be straight up and down, and smooth. Make a mark on the uphill portion of one corner of your pit with your shovel blade. This will mark the boundaries of your column, which should be roughly 30 cm by 30 cm or 12 inches square. (A) Now, cut both sides using a snow saw or your ski, all the way to the floor of the pit making sure that the cuts are straight. (B) The back of the column should only be cut as deep as your shovel blade is long, so measure with your shovel blade (C) and then cut the back. (D) Next, insert your shovel, blade down, in the back cut of the column and pull gently and evenly forward being careful not to lever your shovel handle. (E) Examine the shear layer where the block failed. (F) The force applied to the shovel that causes a weak layer to shear from the layers surrounding it can be rated as follows: Very easy ... Easy ... Moderate ... Hard ...  4, record 1, English, - shovel%20shear%20test

Shovel tilt test... To test for weak layers near the top of the snowpack, cut a square column with sides about 30 centimetres(12 inches) wide. Pick up the top 30-40 centimetres(12-16 inches) of the column on your shovel, tilt the shovel blade to about 15° and tap the bottom of the shovel with your hand, gently at first, then harder. Weak layers within the snow block will show up as smooth fractures.  4, record 2, English, - shovel%20burp%20test

Do not confuse the "burp test" with the "burp the baby test" which can be described as follows: "... completely isolate a column. Then tip the column toward you, rest it against your shoulder and pat the back of the column with your hand like burping a baby (Tremper, B.

Essai par tapotement. Afin de vérifier la présence éventuelle de couches fragiles près de la surface du manteau neigeux, dégagez un carré de neige d'environ 30 cm (12 pouces) de chaque côté. À l'aide d'une pelle, soulevez la tranche supérieure de 30 cm (de 12 pouces à 16 pouces) et tapotez sous la pelle, légèrement d'abord puis avec plus de fermeté (ensuite). Les couches fragiles du bloc seront ainsi révélées et prendront l'aspect de ruptures uniformes.  4, record 2, French, - test%20par%20tapotement
