In reply to Removed Usersmm:
I think that it may be useful to consider a distinction between stuff left at a site by bereaved individuals following someones death there, and stuff left there after someone died somewhere else.
In the former scenario, people come to grieve, to ponder, to remember, to try and make sense of the incident. The news of the death reaches people at different times, but it is usually in the days immediately after the death, and before cremation and burial. People are still in a state of shock. The 'rubbish' left there accumulates over a week or so, and is left by people who are often strangers to one another. Frequently, a person/persons in their number will have the sensitivity to recognise that the 'rubbish' should, out of common decency, be removed, and will do this unobtrusively and gradually over the following week.
By the time of the cremation, grieving of a different form takes place.
By contrast, in the latter, the 'party' heading for an outdoor location to dispose of the ashes, seems commonly to do so because someone in that party has decided on the site, and is deferred to. The site is an afterthought, and in those cases where the rubbish is left , merely somewhere to play out the disposal process. After all, the death was some time ago, and if the individuals couldn't be bothered to choreograph it properly, to consider for one moment what would happen to the stuff they left in a public place , once they had walked away, then it hardly deserves the description of ceremony or ritual.
I am not for one moment claiming that one group has greater claim to leave rubbish than the other. We have to share the mountains with some insensitive people who leave rubbish for all sorts of reasons. Sometimes, with a little inside knowledge, we might emphathise, and check if it needs removing the following week, at other times, it might be more appropriate to shift the rubbish once the disposal party has gone.
