In a slow cooker, add ham bone, skin, trimmings, and water; cover and simmer for at least 10 hours, up to 24 hours. (You can add more ham if your bone isn't meaty enough)

Let cool. Remove fat cap (if any), bones, shred the meat and add back to the broth

Turn slow cooker back on. Rinse split peas and add to broth. Add onions, garlic, bacon ends.

Add the rest of the ingredients (except carrots) and cook on low for 8 hours. Add carrots and cook an additional 4 hours.
