He was carried nearly 2,000 feet to the base of the mountain and was not successfully rescued. Classification
European avalanche risk
In Europe, the avalanche risk is widely rated on the following scale, which was adopted in April 1993 to replace the earlier non-standard national schemes. Descriptions were last updated in May 2003 to enhance uniformity.In France, most avalanche deaths occur at risk levels 3 and 4. In Switzerland most occur at levels 2 and 3. It is thought that this may be due to national differences of interpretation when assessing the risks. [1] Stability:

Generally described in more detail in the avalanche bulletin (regarding the altitude, aspect, type of terrain etc. )[2] additional load:

heavy: two or more skiers or boarders without spacing between them, a single hiker or climber, a grooming machine, avalanche blasting
light: a single skier or snowboarder smoothly linking turns and without falling, a group of skiers or snowboarders with a minimum 10 m gap between each person, a single person on snowshoesGradient:

gentle slopes: with an incline below about 30°
steep slopes: with an incline over 30°
very steep slopes: with an incline over 35°
extremely steep slopes: extreme in terms of the incline (over 40°), the terrain profile, proximity of the ridge, smoothness of underlying ground

North American Avalanche Danger Scale
In the United States and Canada, the following avalanche danger scale is used. Descriptors vary depending on country.
Patients with MD are reluctant to associate their physical symptoms with an affective disorder and refuse mental health care. As a rule, these patients attribute their disturbances to physical illness, seek medical care for them, and report only somatic complaints to their physicians, with the consequence that many of such depressions are not recognized or are misdiagnosed and mistreated Estimates of depressed patients who are correctly identified and treated range from 5% to 60%. Data show that about 10% of people who consult a physician for any reason, originally has affective disorders disguised by physical symptoms. Official diagnostic status
Current classifications: ICD-10 and DSM-5  do not contain the term "masked depression". Some Ukrainian psychiatrists claim that MD is to be qualified as "depression with somatic symptoms" in the ICD-10 (F 3x.01). This means that those who struggle with masked depression often have more physical symptoms such as back pain, abdominal pain, headaches, and even pain during sexual activity or painful periods. For those with more clinical depression, while they still may have physical symptoms, their symptoms are usually more mental or emotional. This includes feelings of helplessness, extreme and/or persisting sadness, numbness, tiredness, drowsiness, exhaustion, and even suicidal thoughts or feelings. Diagnostic criteria
Affective disorders in patients with MD can only be detected by means of a clinician-administered diagnostic interview. : 408 : 576  Organic exclusion rules and other criteria are used in making the diagnosis of MD.
