Please stop. If you continue to add promotional or advertising material to Wikipedia, as you did at Sierra Nevada, you may be blocked from editing. Dora the Axe-plorer (explore) 01:36, 18 March 2023 (UTC)

Just by coincidence, I happen to be a mountaineer active in the Sierra Nevada since the 1970s, as well as a Wikipedia administrator. Please read Spam. Adding a link to a commercial guide service is not permitted and you will be blocked if you persist. On the other hand, you can stop spamming and make positive contributions to articles about mountaineering in the Sierra Nevada instead. I hope you will choose that course.
